【Example】
A first embodiment of the present invention will be described below with reference to the drawings.
(Configuration of Example)
The amorphous mixed material W used in the present embodiment is an irregular and irregular size waste obtained by crushing a vehicle with a crushing means such as a shredder. Therefore, for the irregular shaped mixed material W, large crushed pieces (size: for example 30 to 50 cm), small crushed pieces (size: for example 1 μm to 10 mm), hard crushed pieces such as metal, crushed pieces such as resin and rubber, etc. Are mixed.
[0011]
The hopper 1 is attached to the base 2 in a box shape. The hopper 1 includes a hopper chamber 10 having an upper surface opening 10 p into which the irregular shaped mixed material W is charged, and a discharge port 12 provided at one end of the hopper chamber 10 so as to communicate with the hopper chamber 10.
The discharge port 12 is an opening for discharging the amorphous mixed material W to the outside of the hopper 1. The opening height of the discharge port 12 is defined by a fixed first gate 14 provided on the wall 1 n of the hopper 1. In addition, 1k is a side plate at the end of the hopper 1 in the width direction.
[0012]
The hopper 1 is equipped with a transport means 3 for transporting the amorphous mixed material W. The conveying means 3 includes a driving pulley 30 provided on the discharge port 12 side, a driven pulley 31, a flat belt-like conveying belt 32 that functions as a conveying portion provided on the driving pulley 30 and the driven pulley 31, and a conveying belt. A main drive motor 33 that can function as a drive source for 32, a continuously variable transmission 34 that shifts the driving force of the main drive motor 33 and transmits it to the drive pulley 30, and the main drive motor 33 and the transmission 34. An endless transmission member 35 laid between them, and a transmission member 36 laid between the main drive motor 33 and the drive pulley 30 are provided. If the speed ratio in the transmission 34 is adjusted, the transport speed of the transport belt 32 can be adjusted.
[0013]
A scraping roller 4 is rotatably provided outside the discharge port 12. The scraping roller 4 includes a horizontal shaft type rotating roller 40 and a blade 41 protruding from the outer peripheral portion of the rotating roller 40. The shape and arrangement of the blades 41 can be selected as appropriate. The scraping roller 4 is rotationally driven by an endless transmission member 44 by a drive motor 43 fixed to a fixed base 42 of the hopper 1.
[0014]
A manual second gate 16 that can be moved up and down is located in the hopper chamber 10 in front of the discharge port 12. Between the 1st gate 14 and the 2nd gate 16, the 1st leveling roller 5 which can be rotated is located in the hopper chamber 10, and is equipped. The first stirrer roller 5 includes a horizontal shaft type rotary roller 50 and a blade 51 projecting from the outer peripheral portion of the rotary roller 50.
[0015]
A guide portion 54 for guiding the first stirring roller 5 in the height direction is provided, and a fixing portion 55 for fixing the first stirring roller 5 at an arbitrary height position is provided. Thereby, the height position of the 1st stirring roller 5 can be adjusted. The first leveling roller 5 is adjustable in height, but may be fixed.
The rotation roller 50 of the first stirring roller 5 is rotationally driven by an endless transmission member 57 by a first drive motor 56 fixed to the fixed base 1 s of the hopper 1. VA is set to be faster than VB, where VA is the peripheral speed at the tip of the blade 51 of the first stirring roller 5 and VB is the transport speed of the transport belt 32. The speed ratio is, for example, VA: VB = (60-100): 1. The reason is that it is advantageous to forcibly and effectively bias the upper part of the amorphous mixed material W conveyed in the direction of the arrow X1 by the conveying belt 32 in the direction of the arrow X2 in consideration of the line capability. Because. Of course, the ratio of VA: VB is not limited to the above-described value. Since the transport speed of the transport belt 32 can be adjusted by the transmission 34 of the present embodiment, VA: VB can be adjusted as appropriate.
[0016]
In use, the amorphous mixed material W crushed by a crushing means such as a shredder is charged into the hopper chamber 10 of the hopper 1. The main driving motor 33 conveys the conveying belt 32 toward the discharge port 12, that is, in the direction of the arrow X1. Accordingly, the amorphous mixed material W charged in the hopper chamber 10 is placed on the transport belt 32 and transported toward the discharge port 12 in the direction of the arrow X1. Further, the scraping roller 4 is rotated by the drive motor 43 in the direction of the arrow R1. Therefore, among the plurality of blades 41 of the scraping roller 4, the lower-side blades cause the amorphous mixed material W to be scraped in the same direction as the transport direction by the transport belt 32, that is, in the direction of the arrow X <b> 1. It is discharged outward.
[0017]
The first drive motor 56 rotates the first leveling roller 5 in the direction of arrow R2 (the direction opposite to the direction of arrow R1). Therefore, the upper part of the amorphous mixed material W conveyed by the conveying belt 32 by the lower blade of the plurality of blades 51 of the first stirring roller 5 is in the direction opposite to the conveying direction of the conveying belt 32. In other words, it is biased in the direction of the arrow X2 and is prevented from moving toward the discharge port 12.
[0018]
Therefore, according to the present embodiment, the upper part of the irregular shaped mixed material W conveyed toward the discharge port 12 by the conveying belt 32 is leveled, and the excessive stacking thickness of the irregular shaped mixed material W is regulated. As a result, the amorphous mixed material W is fed to the discharge port 12 in a properly suppressed state even when the stacking thickness is excessive.
Then, the irregularly mixed material W is scraped by the blades 40 of the scraping roller 4, and is discharged to the outside of the hopper 1 through the driving pulley 30. The discharged amorphous mixed material W is used in a subsequent process.
[0019]
(Effect of Example)
As described above, according to the present embodiment, the lower part of the amorphous mixed material W placed on the transport belt 32 is transported toward the discharge port 12. However, the upper part of the irregular shaped mixed material W conveyed toward the discharge port 12 by the conveying belt 32 hits the first stirring roller 5, and the first stirring roller 5 causes the discharge port in the direction of the arrow X 2. It is energized in the direction away from 12, and direct conveyance to the discharge port 12 side is restricted.
[0020]
Therefore, according to the present embodiment, even when the stacking thickness of the amorphous mixed material W transported toward the discharge port 12 by the transport belt 32 is excessive, the stacking thickness is leveled. As a result, the amorphous mixed material W is fed to the discharge port 12 in a state in which the stacking thickness is appropriately suppressed. Therefore, the amorphous mixed material W is quantitatively discharged from the discharge port 12 per unit time. It is advantageous to do. Therefore, the recycling process in the post process becomes easy, which is advantageous for stabilizing the quality of the recycled product.
[0021]
According to this embodiment, the second gate 16 that can be raised and lowered is provided in front of the first stirring roller 5. Therefore, since the upper part of the irregular shaped mixed material W conveyed toward the discharge port 12 by the conveying belt 32 is scraped by the lower end portion 16d of the second gate 16, the loading thickness of the irregular shaped mixed material W is increased. This is even more advantageous. Therefore, even when the stacking thickness of the irregular shaped mixed material W on the conveyor belt 32 is excessive, it is further advantageous for regulating the stacking thickness. The lower end 16d of the second gate 16 may be positioned above the center axis P1 of the first leveling roller 5, or may be positioned below the center axis P1. .
[0022]
(Second embodiment)
FIG. 2 shows a second embodiment. This embodiment basically has the same configuration as that of the first embodiment shown in FIG. However, in this embodiment, in addition to the first stirring roller 5, the second stirring roller 6 is rotatably provided. The second stirring roller 6 includes a horizontal shaft type rotating roller 60 and a blade 61 protruding from the outer peripheral portion of the rotating roller 60. The shape and arrangement of the blades 61 of the second stirring roller 6 can be changed as appropriate.
[0023]
The second leveling roller 6 is further away from the discharge port 12 than the leveling roller 5. The center axis P2 of the second leveling roller 6 can be set at a position higher than the center axis P1 of the leveling roller 5, but in some cases, it may be set at a position lower than the center axis P1. .
In use, the transport belt 32 is transported toward the discharge port 12, that is, in the direction of the arrow X1, as described above. The first leveling roller 5 is rotated in the direction of the arrow R2. The second stirring roller 6 is also rotated in the same direction, that is, in the direction of the arrow R2.
[0024]
The upper part of the amorphous mixed material W conveyed in the direction of the arrow X1 by the conveying belt 32 is reversed in the direction opposite to the conveying direction by the conveying belt 32 by the second stirring roller 6 that rotates in the direction of the arrow R2. Energized in the direction of arrow X2. Thereby, the stacking thickness of the amorphous mixed material W is leveled.
As can be understood from FIG. 2, the upper portion of the amorphous mixed material W whose thickness is stacked by the second stirring roller 6 is conveyed by the first stirring roller 5 rotating in the direction of the arrow R <b> 2. 32 is urged in the direction opposite to the conveying direction, that is, in the direction of the arrow X2. Thereby, the stacking thickness of the amorphous mixed material W is further increased. Therefore, it is advantageous to discharge the amorphous mixed material W quantitatively from the discharge port 12 per unit time.
[0025]
(Third embodiment)
FIG. 3 shows a third embodiment. The present embodiment is basically the same configuration as the first embodiment. However, in this embodiment, in addition to the first stirrer roller 5, a second stirrer roller 6 and a third stirrer roller 7 are rotatably provided. The second stirring roller 6 includes a horizontal shaft type rotating roller 60 and a blade 61 protruding from the outer peripheral portion of the rotating roller 60. The third stirring roller 7 includes a horizontal axis type rotating roller 70 and a blade 71 projecting from the outer peripheral portion of the rotating roller 70. The shape and arrangement of the blades 61 of the second stirring roller 6 and the shape and arrangement of the blades 71 of the third stirring roller 7 can be changed as appropriate.
[0026]
The second leveling roller 6 is further away from the discharge port 12 than the leveling roller 5. The center axis P2 of the second stirring roller 6 can be set to a position higher than the center axis P1 of the first stirring roller 5, but may be set to a lower position depending on circumstances. The third stirring roller 7 is further away from the discharge port 12 than the second stirring roller 6. The center axis P3 of the third stirring roller 7 can be set at a position higher than the center axis P2 of the second stirring roller 6, but may be set at a lower position in some cases.
[0027]
In use, the transport belt 32 is transported toward the discharge port 12, that is, in the direction of the arrow X1, as described above. The first leveling roller 5 is rotated in the direction of the arrow R2. The second stirring roller 6 is rotated in the same direction, that is, in the direction of the arrow R2. The third stirring roller 7 is also rotated in the same direction, that is, in the direction of the arrow R2.
Therefore, the upper part of the amorphous mixed material W conveyed by the conveying belt 32 in the direction of the arrow X1 is first leveled by the third stirring roller 7 and then leveled by the second stirring roller 6. Then, it is smoothed by the first stirring roller 5. As a result, the stacking thickness of the amorphous mixed material W is further flattened. Therefore, it is advantageous to discharge the amorphous mixed material W quantitatively from the discharge port 12 per unit time.
[0028]
(Fourth embodiment)
FIG. 4 shows a fourth embodiment. This embodiment has basically the same configuration as that of the third embodiment shown in FIG. However, in this embodiment, the second stirring roller 6 rotates in the direction of arrow R1, which is the opposite direction to the direction of rotation of the first stirring roller 5 and the third stirring roller 7 (direction of arrow R2). Is done.
[0029]
The upper part of the amorphous mixed material W conveyed by the conveying belt 32 in the direction of the arrow X1 is first reversed in the direction opposite to the conveying direction by the conveying belt 32 by the third stirring roller 7 rotating in the direction of the arrow R2. That is, it is urged in the direction of arrow X2. Thereby, the stacking thickness of the amorphous mixed material W is leveled.
Thereafter, the irregularly shaped mixed material W whose thickness is stacked in this way is urged in the direction of the arrow X1 toward the discharge port 12 by the second stirring roller 6 that rotates in the direction of the arrow R1.
[0030]
Next, the first stirring roller 5 rotating in the direction of arrow R2 is urged in the direction opposite to the conveyance direction by the conveyance belt 32, that is, in the direction of arrow X2. Thereby, the stacking thickness of the amorphous mixed material W is leveled.
(Development drawing of the blade of the stirring roller)
(1) When the irregular shaped mixed material W is loaded on the conveyor belt 32 of the hopper 1, the loaded thickness of the irregular shaped mixed material W is generally set to the width of the hopper 1 as shown in FIG. It presents a mountain shape that becomes a high peak Wa in the central area of the direction. However, in order to improve the quantitative discharge property of the irregular shaped mixed material W, the form in which the top portion Wa of the irregular shaped mixed material W is broken as shown in FIG. 6 (B), or as shown in FIG. 6 (C). A form in which the stacking thickness of the shaped mixed material W is uniform in the width direction of the hopper 1 is preferable.
[0031]
Therefore, the arrangement of the blades in the above-described stirring roller can be improved as illustrated in FIGS. 5A to 5D as development views.
{Circle around (2)} In the developed form of the blade arrangement shown in FIG. 5A, the blades A to G are arranged so as to exhibit a V shape in which the interval L1 expands along the circumferential direction of the roller. Therefore, when the irregular shaped mixed material W is conveyed by the conveying belt 32 in the direction of the arrow X1, the irregular shaped mixed material W hits the blade A → the blade B → the blade C → the blade D → the blade E → the blade F → the blade G in order. As described above, the leveling roller is disposed in the hopper 1. Therefore, it becomes advantageous to guide the amorphous mixed material W conveyed in the arrow X1 direction in the arrow M1 direction using the blades A to G. That is, it is advantageous for bending the amorphous mixed material W in the direction of the arrow X1 that is the conveyance direction by the conveyance means.
[0032]
In other words, the blades A to G according to FIG. 5 (A) have the function of bringing the irregular shaped mixed material W from the center side SA of each stirring roller to the shaft end side SB and breaking the mountain-shaped top portion Wa. Play. Thereby, even when the irregularly shaped mixed material W is loaded in a mountain shape having the top portion Wa, the excessively high top portion Wa is effectively destroyed, which is advantageous for flattening the height of the irregularly shaped mixed material W. Become. Therefore, it becomes more advantageous for quantitative discharge of the irregular shaped mixed material W.
[0033]
(3) The arrangement shown in FIG. 5 (B) is basically the same as the arrangement shown in FIG. 5 (A), and has the function of breaking the top portion Wa of the amorphous mixed material W. That is, in the arrangement shown in FIG. 5B, the blades A to G are arranged so as to exhibit a V shape in which the interval L2 expands along the circumferential direction of the roller. However, the blades G are inclined so that the rear end G1 thereof faces the center of the roller shaft.
[0034]
In the arrangement shown in FIG. 5B, when the irregular shaped mixed material W is conveyed in the direction of the arrow X1 by the conveying belt 32, the blade A → the blade B → the blade C → the blade D → the blade E → the blade F → the blade G. In this order, a leveling roller is arranged in the hopper 1 so that the irregular shaped mixed material W is hit. Therefore, it is advantageous to guide the irregular shaped mixed material W conveyed in the direction of the arrow X1 in the direction of the arrow M1, that is, the irregular shaped mixed material W is moved from the center side SA to the shaft end side of each stirring roller. May be sent to SB. Thereby, the top part Wa of excessive height is destroyed, and it becomes advantageous for the flattening of the height of the amorphous mixed material W. In the arrangement shown in FIG. 5B, the blade G causes the amorphous mixed material W to be slightly moved in the direction of the arrow M2, that is, the center side of the roller axis.
[0035]
(3) In the blade arrangement shown in FIG. 5 (C), the blades A to G are inclined and arranged so as to exhibit a V-shape in which the interval L3 is expanded along the circumferential direction of the roller. And the blade | wing A-the blade | wing E are arranged in the direction orthogonal to the roller axial center of a stirring roller. In the blade arrangement shown in FIG. 5C, the blades F and G are inclined so that rear ends F1 and G1 face the center of the roller axis.
[0036]
In the blade arrangement example shown in FIG. 5 (C), it is arranged along the arrow X1 direction, which is the conveying direction of the amorphous mixed material W. Therefore, when the amorphous mixed material W is conveyed in the arrow X1 direction, Although the blades A to E basically have a function of causing the amorphous mixed material W to run straight in the direction of the arrow X1, which is the conveyance direction, basically, the amorphous mixed material W is not bent in the direction of the arrow M1. . In addition, the blades F and G, which are inclined as shown in FIG. 5C, have a function of bringing the amorphous mixed material W in the direction of the arrow M2, that is, toward the center side of the stirring roller.
(4) In the blade arrangement shown in FIG. 5 (D), the blades A to G are inclined and arranged so as to exhibit a V-shape in which the interval L4 is expanded along the circumferential direction of the roller. The blades A to G are arranged in a direction orthogonal to the roller axis of the stirring roller, that is, arranged along the direction of the arrow X1, which is the conveyance direction of the amorphous mixed material W. Yes. Therefore, in the example shown in FIG. 5D, when the amorphous mixed material W is transported in the direction of the arrow X1, the blades A to G basically move the amorphous mixed material W in the direction of the arrow X1 (conveying means). However, the amorphous mixed material W is not bent so much in the direction of the arrow M1.
