Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting conveyor suitable for sorting granular materials, and more particularly to an object to be processed in which a light-weight object having a small specific gravity and a heavy object having a large specific gravity are mixed. And a sorting conveyor for sorting according to purpose.

[0002]

2. Description of the Related Art In general, construction waste materials that have been dismantled, such as concrete waste materials, include materials that can be reused as resources such as concrete, stone, sand, etc., as well as wood chips, embi tubes, vinyl,
Includes waste, plastics, paper, and other items that are disposed of by landfilling or incineration.

[0003] As a method of sorting such construction waste materials,
First, there is a method of manual selection. However, in the manual selection method, there is a limit to a processing amount due to danger of being caught in a line, work restriction due to dust or the like, and fatigue. For this reason, apart from a specific sorting process that only depends on humans, a sorting process by a machine is widely performed at present.

[0004] Sorting processing by such a machine includes:
For example, various methods such as an ink line method, a vibration / wind force selection method, a tilt type selection method, and a rotating brush method have been developed. The ink-line type sorting apparatus has a configuration in which an inclined conveyor and a rotary chain curtain are combined. Further, the sorting apparatus of the vibration / wind sorting method is configured to loosen an object to be processed by vibration, and to separate and sort using an ejection power / suction force of a blower or a suction machine. The sorting device of the inclined type sorting system utilizes the ease of rolling of the slope mainly related to the weight of the object to be processed, and has a configuration of separating and sorting using a roller conveyor or a disc for ascending transport. .

[0005] As a rotary brush type sorting device,
Japanese Patent Application Laid-Open No. Sho 62-57 discloses a device comprising a pair of rotating brushes.
687. In this sorting device, when an object to be processed is dropped on a brush, a light-weight object to be processed is carried by a rotating brush in a tangential direction substantially perpendicular to a brush rotation axis, while a heavy object to be processed having a large specific gravity is rotated by a rotating brush. Fall from the gap. As a result, the light-weight workpiece and the heavy-weight workpiece are sorted out.

[0006]

Among the above-mentioned conventional sorting apparatuses, the sorting apparatuses of the ink line type, the vibration / wind type, and the tilt type sorting type all carry the object to be processed over a relatively long distance. When transporting or installing a large output drive source is required, large-scale equipment remodeling is required when attaching to existing equipment, and the sorting apparatus itself becomes expensive. Furthermore, a burden is imposed on the increase in power consumption,
In some cases, capital investment other than the sorting device itself may be required.
In the case of wind power, useful materials such as fine aggregate and sand are often sorted to the disposal side.

[0007] On the other hand, the above-mentioned rotary brush type sorting apparatus can reduce the cost of the sorting apparatus itself as compared with the other types, and requires only power for brush rotation. There is an advantage that the extension does not impose a large burden and noise and vibration are relatively small. However, on the other hand, there is a problem that the separation / recovery rate is reduced when the transfer length of the object to be processed by the rotating brush is reduced.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sorting conveyor capable of reliably separating and recovering while keeping the installation space and the required output of a driving source small.

[0009]

According to a first aspect of the present invention, there is provided a sorting conveyor for sorting an object to be processed according to its size, specific gravity, and shape. A conveyor having a first transport belt for placing and transporting an object to be processed, and a rotary brush having brush bristles planted on the outer circumference of a rotary shaft installed substantially parallel to the transport direction above the transport belt; A substantially arc-shaped portion formed along the outer periphery of the rotating brush when the rotating brush rotates, covering the surface of the rotating brush other than the surface facing the first transport belt; A casing formed of a lower half of the arc-shaped portion so as to be guided outside the conveyor belt and a guide portion connected to a quadrant along the upward rotation outer periphery of the rotary brush, and conveyed by at least the rotary brush. A protrusion is provided on the improvement flow side and protrudes in the radial direction on the outer peripheral surface, and the outer peripheral surface is brought into contact with the first transport belt and rotated to apply vibration to the first transport belt. (1) a vibrating roller, an inclined separation conveyor which is arranged in a slanting position directly below the processing object sending-out port of the guide section, and which is an ascending conveyance direction, and which is arranged before and after a processing object supply position of the inclined separation conveyor, and is arranged in a radial direction. A second vibrating roller for applying vibration to the inclined separation conveyor by rotating the outer peripheral surface having the protruding projection formed thereon in contact with the back surface of the second conveyor belt of the inclined separation conveyor. I do.

[0010] In this sorting conveyor, first, a rotating brush is slidably brought into contact with the workpiece on the first conveyor belt, thereby rotating up the lightweight workpiece in the workpiece to thereby lift the lightweight workpiece. And the heavy workpiece. That is, the upper layer on the first conveyor belt is in a state where almost all of the lightweight workpiece and a part of the heavy workpiece are mixed. Most of the light-weight workpieces, in which the heavy workpieces are mixed in a part thereof, are immediately discharged from the first conveyor belt through the guide portion which is in sliding contact with the rotating brush and which is connected to the quadrant of the casing. That is,
The once-raised lightweight workpiece does not rotate and move along the outer circumference of the rotating brush for a long distance. As a result, most of the lightweight workpiece is reliably taken out. Then, a part of the heavy workpiece mixed with the lightweight workpiece is separated by the subsequent inclined separation conveyor. As a result, a high sorting ability with no leftover of the lightweight workpiece can be obtained.

The inclined separation conveyor is supplied from the guide portion of the casing with a light-weight workpiece in which a heavy workpiece is mixed in a part which is picked up by the rotating brush. The conveying belt of this inclined separation conveyor is vibrated by the second vibrating roller in the ascending conveyance direction, and the object to be processed which has been jumped up by the vibration rolls down to the upstream side of the inclined separation conveyor due to the inclination. The heavy workpiece is rolled down as it is, but the lightweight workpiece is gradually transported in the ascending direction by being dragged by the movement of the second transport belt of the inclined separation conveyor. Accordingly, the heavy workpiece is sorted upstream of the inclined separation conveyor, and the light workpiece is sorted downstream of the second conveyor belt, and the heavy workpiece is separated and removed from the lightweight workpiece. As a result, most of the lightweight workpiece is removed from the first conveyor belt, and the separation and recovery rate increases.

The sorting conveyor according to claim 2 is provided upstream of the guide portion of the quadrant arc portion in the rotation direction of the rotating brush, and is conveyed by the side of the loading surface of the first conveyor belt. A rotary scraping brush for scraping an object and sending it to the guide portion is provided.

In the sorting conveyor, the scraping brush scoops up the light-weight workpiece and the heavy workpiece on the side of the loading surface of the conveyor belt, which are hard to slide on the rotating brush. In other words, most of the light-weight workpieces in which the heavy workpieces are mixed in a part of the pre-process performed by the rotating brush are immediately discharged from the guide portion. As a result, the problem that the object to be processed, which has approached the side of the loading surface of the conveyor belt, passes through without being scraped is less likely to occur, and the separation and recovery rate is increased.

According to a third aspect of the present invention, the sorting conveyor is provided with a fixed brush arranged at the uppermost stream of the inclined separating conveyor, and for passing only an object to be processed having a predetermined weight or more in a downward direction of the inclined separating conveyor. And

In this sorting conveyor, the object to be processed, which is jumped up by the vibration of the second conveyor belt of the inclined separation conveyor and rolls down to the upstream of the belt movement, which is the downward direction of the inclined separation conveyor, is moved by such a fixed brush. Once stopped. At this time, a heavy object to be processed that is too heavy for the rigidity of the fixed brush to roll off from the upstream side of the inclined separation conveyor, that is, is sorted out. Further, the light-weight workpiece pressed by the fixed brush is transported downstream by the movement of the second transport belt, is again exposed to vibration, and rolls down to some extent, but some of the second transport belt does not reach the fixed brush. , And are discharged from the downstream side of the inclined separation conveyor and sorted. In this way, it is possible to more reliably sort the heavy and light workpieces.

According to a fourth aspect of the present invention, there is provided the sorting conveyor according to the second aspect,
Among the vibrating rollers, the vibration driven roller that is disposed upstream of the processing object supply position is driven by the inclined separation conveyor, and the vibration driven roller that is disposed downstream of the processing object supply position is driven by a faster rotation than the driven roller. A vibration-driven pulley.

In this sorting conveyor, a vibration driving pulley driven at a speed higher than that of the vibration driven roller is disposed downstream of the processing object supply position, so that a processing object having a small particle size or a flat processing object can be removed. By giving a sufficient vibration, the object to be treated having a small particle size can be retained at the position by appropriately adjusting the vibration frequency. A flat object can be reliably rolled if it is a heavy object, and can be prevented from being sorted on the lighter side.

According to a fifth aspect of the present invention, there is provided a sorting conveyor, comprising a claw member provided at a boundary between the casing and the guide portion, disposed on the outer periphery of rotation of the rotating brush, and having a tip protruding into the guide portion. It is characterized by having.

In this sorting conveyor, the claw member is arranged on the outer circumference of the rotating brush, and the tip protrudes into the guide portion. Therefore, the light-weight object (such as vinyl dust or cloth dust) that is caught on the outer periphery of the rotating brush is caught on the claw member and is removed from the rotating outer periphery of the rotating brush. Since the tip of the claw member protrudes into the guide portion, the light-weight workpiece to be caught by the claw member is released from being caught only in a direction in which it falls into the guide portion. That is, it is reliably dropped into the guide portion. This allows
It is possible to remove the light-weight object to be caught on the outer periphery of the rotating brush.

The sorting conveyor according to claim 6 is provided radially on a rotating shaft in the same direction as the rotation center of the rotating brush, and the plurality of rotating conveyors are driven around the rotating shaft in the same direction as the rotating brush. A claw member is provided.

In this sorting conveyor, the plurality of claw members are rotated in the same direction as the rotating brush while contacting the outer circumference of the rotating brush. That is, the light-weight object to be caught on the outer periphery of the rotating brush is more positively removed by the claw member. When the claw member on which the lightweight object is hooked on the outer periphery of the rotating brush is rotated and moved into the guide portion, the lightweight object is dropped into the guide portion. This operation is performed continuously with the rotation of the claw member.

According to a seventh aspect of the present invention, in the sorting conveyor, the first
A brush belt provided above and intersecting the conveyor belt, and brush bristles implanted on the outer peripheral surface of the endless flat belt slidably in contact with an object to be processed on the first conveyor belt; And a magnet disposed inside the circuit, for causing the iron material conveyed on the first conveyor belt to be attracted to the outer peripheral lower surface of the brush belt and conveyed.

In this sorting conveyor, when a brush belt provided above and crossing the first conveyor belt is driven to rotate, the object to be processed in the upper layer of the first conveyor belt is swept by the brush bristles of the brush belt. And is swept out of the first transport belt. At this time, the iron material is attracted to the brush belt and simultaneously swept out by the magnetic attraction of the magnet. The iron material adsorbed on the brush belt drops downward from the end of the brush belt in the transport direction because the magnetic attraction force from the magnet decreases at the end of the brush belt. As a result, the workpiece including the iron material is separated from the workpiece transported by the first transport belt.

The sorting conveyor according to the present invention is characterized in that the sorting conveyor is provided with an inclined separation conveyor which is inclined and disposed immediately below the end of the brush belt in the conveying direction of the iron material and is in the ascending conveying direction.

In the sorting conveyor, the objects to be processed, which have been swept out by the brush belt, are fed into the inclined separation conveyor. The processing object put into the inclined separation conveyor, the aggregate of a predetermined weight or more is rolled back in the direction of conveyance,
Separated from the lightweight workpiece. On the other hand, the light-weight workpiece is transported in the upward transport direction of the inclined separation conveyor. As a result, the aggregate and other foreign matter are separated.

According to a ninth aspect of the present invention, there is provided a sorting conveyor for sorting an object to be processed, the conveyor having a first conveyor belt for placing and conveying the object, and a radially projecting projection. A first vibrating roller, which is formed on a surface of the first conveying belt and applies vibration to the first conveying belt by rotating the outer peripheral surface while contacting the first conveying belt, and intersects above the first conveying belt. The brush bristles provided on the outer peripheral surface of the endless flat belt are arranged inside the endless peripheral circuit of the brush belt, in which the brush bristles slidably contact the object to be processed on the first conveyor belt, A magnet for adsorbing and transporting the iron material transported on the first transport belt to the outer peripheral lower surface of the brush belt, and a tilt separation, which is inclined and disposed immediately below the workpiece outlet of the brush belt and is an upward transport direction. Conveyor and the slope The inclined separation conveyor is arranged by rotating an outer peripheral surface, which is disposed before and after the workpiece supply position of the separation conveyor and has a projection protruding in the radial direction, in contact with the back surface of the second conveyor belt of the inclined separation conveyor and rotates. And a second vibrating roller for imparting vibration to the motor.

In this sorting conveyor, when a brush belt provided above and crossing the first conveyor belt is driven to rotate, the object to be processed in the upper layer of the first conveyor belt is swept by the brush bristles of the brush belt. And is swept out of the first conveyor belt onto an inclined separation conveyor. At this time, the iron material is attracted to the brush belt and simultaneously swept out by the magnetic attraction of the magnet. The iron material adsorbed on the brush belt drops downward from the end of the brush belt in the transport direction because the magnetic attraction force from the magnet decreases at the end of the brush belt. As a result, the workpiece including the iron material is separated from the workpiece transported by the first transport belt and supplied to the inclined separation conveyor. The object to be processed supplied to the inclined separation conveyor is vibrated by the second vibrating roller because the conveyance belt of the inclined separation conveyor is vibrating by the second vibration roller in the ascending conveyance direction. Due to the inclination, it rolls down to the upstream side of the inclined separation conveyor. The heavy workpiece is rolled down as it is, but the lightweight workpiece is gradually transported in the ascending direction by being dragged by the movement of the second transport belt of the inclined separation conveyor. Therefore,
The heavy workpiece is sorted upstream of the inclined separation conveyor, and the light workpiece is sorted downstream of the second conveyor belt, and the heavy workpiece is separated and removed from the lightweight workpiece.

According to a tenth aspect of the present invention, in the sorting conveyor, the pulley on the end side in the transport direction of the inclined separation conveyor is an electromagnetic pulley.

In this sorting conveyor, since the pulley at the end of the inclined separation conveyor in the conveying direction is an electromagnetic pulley,
The iron material such as a track and the like, which are conveyed in the ascending conveying direction of the inclined separation conveyor, and other light objects to be processed are further separated. That is, when these foreign substances reach the end of the inclined separation conveyor in the conveying direction, they fall from this end. At this time, foreign substances such as iron materials which are subjected to the magnetic attraction force are attracted to the electromagnetic pulley and separated by the electromagnetic pulley. After being conveyed by a predetermined distance along the lower surface of the outer periphery of the conveyor, it is dropped. On the other hand, foreign matter other than the iron material is dropped along a parabola at a position separated by a predetermined distance from the end of the inclined separation conveyor by inertial force. Further, the aluminum is scattered farther from the end of the inclined separation conveyor by a magnetic repulsion, drawing a parabola larger than foreign matters other than iron. As a result, the inclined separation conveyor enables four types of separation from aggregates, iron materials, aluminum, and other foreign substances.

The sorting conveyor according to claim 11, further comprising a rotary scraping brush for scraping an object to be conveyed at a side of the loading surface of the first conveyor belt and abutting against the lower surface of the outer periphery of the brush belt. Features.

In the sorting conveyor, an object to be conveyed at the side of the loading surface of the first conveyor belt is scraped up by a scraping brush, and is applied to the outer peripheral lower surface of the brush belt. As a result, the iron material located in the lower layer is dug up at the side of the loading surface of the first transport belt, so that the magnetic attraction force of the magnet acts easily, and the magnet belt is easily attracted by the brush belt.

According to a twelfth aspect of the present invention, there is provided a sorting conveyor, comprising: a receiving hopper into which an object to be processed is charged; a crusher connected to the receiving hopper to crush the object to be charged into the receiving hopper; Connected, the crushed object discharged from the crusher, the object to be treated having a certain size or more, and a sieve for separating the object to be treated having a size less than a certain size, A return conveyor for transporting the separated workpieces of a certain size or more to the crusher side again, and a return conveyor provided before the reloading of the workpieces of the certain size or more to the crusher; And an inclined separation conveyor that is disposed in the direction and rolls down only an object to be processed having a predetermined weight or more to the upstream side in the transport direction.

In this sorting conveyor, an object to be processed put in the receiving hopper is put into a crusher and crushed to a predetermined size. The object to be crushed by the crusher is put into a sieve, and further separated into an object to be processed having a certain size or more and an object to be processed having a size smaller than a certain size. The object to be treated having a certain size or more separated by the sieve is put into a return conveyor, returned to the crusher side again, and crushed by the crusher. Therefore, the object to be processed put into the receiving hopper circulates between these devices until it becomes smaller than a certain size. On the other hand, the object to be processed that has become smaller than a certain size is discharged as an aggregate product from the sieve.

In the sorting conveyor according to the thirteenth aspect, the inclined separation conveyor is disposed in an inclined position immediately below an object loading port of the hopper, and the object to be rolled down in a reverse direction to the conveying direction is introduced into the crusher. It is characterized by being performed.

In this sorting conveyor, the object to be processed put into the receiving hopper enters the inclined separation conveyor disposed immediately below the object input port. Since the inclined separation conveyor is disposed so as to be in the ascending transport direction, the processing object having a predetermined weight or more is rolled back in the transport direction. That is, only the separated objects having a weight equal to or greater than the predetermined weight are introduced into the crusher.
As a result, only the object to be treated after removing non-product raw materials such as wood, vinyl, and cloth, which are lightweight objects to be treated, is efficiently supplied to the crusher.

In this sorting conveyor, an inclined separation conveyor is arranged between the sieve and the return conveyor. An object to be treated having a certain size or more separated by a sieve is charged into the inclined separation conveyor. On the other hand, an object to be processed having a size smaller than a certain size separated by the sieve is transported as a product. Of the objects to be processed having a predetermined size or more, which have been thrown into the inclined separation conveyor, only those having a predetermined weight are rolled down to the upstream side in the transport direction and returned to the return conveyor again. An object to be processed (vinyl, wood piece, cloth, etc.) having a size equal to or larger than a predetermined size and less than a predetermined weight is conveyed in the conveying direction of the inclined separation conveyor, and is treated as foreign matter. Thereby, the object to be processed that has not been crushed to a predetermined size is
While re-crushing is possible, large foreign matter other than the product is separated from the product production line by the inclined separation conveyor.

According to a fifteenth aspect of the present invention, there is provided a composite sorting conveyor, wherein the sorting conveyor according to the first aspect is connected to a stage subsequent to the sorting conveyor according to the first aspect.

In this composite sorting conveyor, claims 11 to
An object to be processed having a size smaller than a predetermined size separated by the sorting conveyor according to any one of the fourteenth aspects is continuously fed into the first transport belt according to the first aspect. In other words, the sorting conveyor according to the first aspect is supplied with a sorting-processed object having a size smaller than the predetermined size. Then, the object to be sorted which is smaller than the predetermined size is removed by a rotating brush, a scraping brush, a second transport belt, and a second vibrating roller provided in the sorting conveyor according to claim 1. Then, separation of the light-weight workpiece and the heavy workpiece is performed.

Numeral 34 has a plurality of projections on its outer peripheral surface. When the first transport belt 31 is driven in a state in which the first transport belt 31 is in contact with the first transport belt 31, each of the first
The vibration rollers 33 and 34 rotate, and the required vibration is applied to the first transport belt 31 by the step between the outer peripheral surface of each roller and each projection. Due to this vibration, the first transport belt 31
The object to be processed vibrates, and the light object to be processed in the object to be processed is lifted to an upper layer due to a difference in specific gravity. The amplitude of the vibration at this time is relatively large (approximately 8 to 12 mm) for the first vibration roller 33 on the upstream side, and is combined with the elastic repulsive force of the first transport belt 31 due to the long roller arrangement pitch. 1
Strong vibration can be applied to the transport belt 31. Further, the first vibration roller 34 on the downstream side can apply a slight vibration to the belt 31.

Next, the sorting device 40 and the inclined separation conveyor 70 of the present embodiment will be described.

You may make it. As a result, the scraping effect on the lightweight workpiece can be enhanced. In addition, the rotating brush 41 is configured to be easily detachable from the rotating shaft 49, thereby facilitating attachment and replacement work.

The brush driving motor 47 includes a rotating brush 41
The torque required for the rotation of the workpiece M
The number of rotations is adjusted as appropriate according to the amount of placement on the transport belt 31 and the like. In the present embodiment, a 0.4 kW motor is

The interval is set. The upper casing 52 has an inner peripheral surface that is continuous with the inner peripheral surface of the lower casing 50. The lower casing 50 discharges the lightweight workpiece scraped up by the rotating brush 41 from an outlet 54 formed in the lower casing 50. In the present embodiment, as shown in FIG. 3, the upper and lower casings 50 and 52, which are formed into a substantially cylindrical shape when combined vertically, have a lower left quarter portion (quadrant arc portion 50a) in the drawing, and A discharge port 54 is opened near the tip of the brush bristles 63 above the raising brush 60. The radius of the upper and lower casings is set to about 300 mm, and the lower casing 50 slides on the lower surface of the first transport belt 31 when the first transport belt 31 sinks due to the weight of the workpiece M. By doing so, the first transport belt 31 is supported.

Next, the inclined separation conveyor 70 connected to the sorting device 40 will be described. As shown in FIGS. 2 and 3, a guide portion (discharge chute) 80 which is a guide portion for a workpiece is connected to the discharge port 54 of the lower casing 50. Immediately below the lower opening 82 of the discharge chute 80,
An inclined separation conveyor 70 having a frame 71 supported by a support member 78 on a conveyor frame 38 is arranged. The inclined separation conveyor 70 includes a second conveyor belt 76 stretched between a belt driving pulley 75 and a rotating roller 74. The second transport belt 76 is driven to transport the workpiece M supplied from the lower opening 82 of the discharge chute 80 in the ascending direction. A guide plate 79 is disposed over the entire length of both sides of the second conveyor belt 76 so that the workpiece does not fall from the side of the second conveyor belt 76.

Further, on the upstream side of the second conveyor belt 76 from a position immediately below the opening 82, a second vibration having the same configuration as the first and second downstream driven rollers 33 and 34 with respect to the first conveyor belt 31 described above. The driven roller 72 is disposed, and the opening 8
A vibration drive pulley 73, which is similar in form to the first vibration driven rollers 33 and 34 and is driven by faster rotation, is disposed downstream of the position immediately below the second conveyance belt 76 from the position of the second conveyance belt 76. At the most upstream position of the second conveying belt 76, in FIG. 2, near the connecting position between the support stem 78 and the frame 71, a fixed brush 77 whose tip is in contact with the second conveying belt 76 is arranged. In addition, instead of the vibration drive pulley 73 employed in this embodiment,
A driven roller similar to the second vibration roller 72 can be used.

The second conveyor belt 76 is a belt drive pulley 7
5, and the vibration is generated by the second vibration driven roller 72 and the vibration driving pulley 73. At this time, when the workpiece M discharged from the lower opening 82 falls on the second conveyor belt 76, if both the heavy workpiece and the lightweight workpiece are easily rolled, they are opposed to the moving direction of the belt. However, by setting the inclination angle of the second transport belt 76 appropriately, the lightweight workpiece stops rolling halfway due to its lightness. In this way, sorting is performed for those that roll and those that do not. Here, an object having a shape that is difficult to roll (for example, a piece of paper, a piece of wood, a piece of flat concrete, or the like) is transported upward by the second transport belt 76. At this time, the second vibration roller 72 and the vibration drive pulley 7 are moved.
Because it is vibrated to the extent that it bounces off due to the vibration of 3, even those that are difficult to roll have a certain amount of weight and begin to roll, and among them, lightweight ones stop rolling immediately, but if they are heavy like concrete pieces, It rolls down and is sorted.

The position of the workpiece M discharged from the lower opening 82 onto the second conveyor belt 76 is preferably at the center of the second conveyor belt 76 in the longitudinal direction. If this position is too far upstream, a situation occurs in which a light-weight workpiece to be rolled easily rolls out together with a heavy workpiece. Further, if the falling position is too downstream, there is a risk that a heavy workpiece having a shape that is difficult to roll is sorted to a light workpiece. The inclination angle of the second conveyor belt 76 is
It is set to 18 ° to 25 °. This is because, when the inclination angle is shallower than 18 °, a heavy object hardly rolls down when the inclination angle is shallower than 18 °, and when the inclination angle is 25 ° or more, the lightweight object is conveyed to the downstream of the second conveyor belt 76. May be lost. At this time, the second transport belt 76
Is preferably 15 to 20 m / min. If the speed is lower than 15 m / min, many light objects will not be able to ride in the ascending direction and will stay on the belt forever. When it is faster than 20m / min,
A heavy object is sorted out to a light object. If the speed is 15 to 20 m / min, only the sand can be retained on the belt and removed at a fixed amount. However, if the speed is higher than 20 m / min, such an effect is lost.

Here, as described above, the fixed brush 77 is arranged at the most upstream position of the second transport belt 76. The fixed brush 77 is provided in the form of a rope curtain, and its strength (strength of the waist) is set to such an extent that a heavy object such as a piece of concrete passes between the curtains. Therefore, although the heavy object to be processed passes through, the light object to be rolled down to the end can be temporarily stopped at this position. Once the lightweight workpiece stops, the second conveyor belt 7
6, and after being rolled and transported several times, it is sorted to the lightweight workpiece.
By such an action, the separation and recovery rate can be increased. The dimensions and the material of the fixing brush 77 are, specifically, preferably about 0.7 mm in the case of a nylon fiber bundle, but are not limited to this as long as it can pass through a heavy object. In addition, besides nylon fiber bundles, vinyl chloride, polystyrene and the like can be suitably used as the material.

Further, as shown in FIG. 2 and FIG. 3, on the inner peripheral surface of the lower casing
A scraping brush 60 is provided. Brush 60
A small rotary brush with brush bristles is attached to the tip of a drive shaft provided to penetrate from the outside to the inside of the lower casing 50. The scraping brush 60 is disposed inside the lower casing 50 on the side of the rotating brush 41 in the scraping direction and at the downstream end of the rotating brush 41 in the transport direction. The scraping brush 60 is provided upstream of the discharge chute 80 of the quadrant arc portion 50 a in the lower casing 50 in the rotation direction of the rotating brush 41. That is, the scraping brush 60 is arranged such that the brush bristles are in sliding contact with the loading surface at the end of the first conveyor belt 31 at the upward rotating portion of the rotating brush 41 as shown in FIG.

FIG. 4 is a schematic perspective view illustrating a scraping brush used in the present invention. This brush 60
In the cross section of the transport path on the downstream side of the transport of the rotary brush 41, the distance between the brush bristle tip of the rotary brush 41 and the workpiece M on the first transport belt 31 becomes large, and the interference between them becomes insufficient. In the region p on the side of the loading surface of the first transport belt 31 which is likely to be, the lightweight workpiece conveyed in this region p is forcibly scraped up in the reverse direction of the transport direction. In other words, the scraping brush 60 has a function of rotating the drive shaft of the scraping brush 60 to scrape the light-weight workpiece in the region p and re-inject it into the rotation locus of the rotating brush 41. As described above, by giving the rotating brush 41 an opportunity to cause interference again, the object to be processed can be more reliably selected.

The brush 60 according to the present embodiment is
Brush bristles are implanted substantially perpendicular to the drive shaft. The material used for the brush bristles is selected so as to obtain the repulsive force and strength necessary to scrape the object to be treated and to scrape it in the circumferential direction of the brush 60. For example, a hard nylon fiber bundle (other than Vinyl chloride, polystyrene) and the like can be suitably used. The brush bristles 63 of the present embodiment rotate while deforming into a shape along the inner peripheral curved surface of the lower casing 50, and can efficiently scrape the workpiece along the inner peripheral curved surface of the lower casing 50.

The direction of rotation of the brush 60 is the clockwise direction in FIG.
The light-weight workpiece is scraped up to the upstream side in the moving direction of the rotating brush 41 and is thrown into the rotation locus of the rotating brush 41. In addition, the wire diameter of the brush bristles of the brush 60 of the present embodiment is 1.2 mm.
And the outer diameter of the brush is set to 250 mm. It is preferable that the rotation speed of the drive shaft be about 77 to 100 rpm from the viewpoint of practical sorting efficiency. In addition, although the case where the brush bristles of the present embodiment are linear brush bristles will be described as an example, the bristles may be formed in a wave shape. In this case, the substantial elasticity of the brush bristles is further improved, and the scraping rate of the object can be increased. Further, a plurality of scraping brushes 60 may be provided, and brushes having different outer diameters may be stacked in a plurality of stages, so that the scraping rate of the workpiece can be increased.

Next, the operation of the sorting by the sorting conveyor 100 of this embodiment will be described. In the sorting conveyor 100, first, the processing object M is placed on the sorting conveyor 100 shown in FIG.
Is supplied to the processing object supply unit 90 on the lower side of the slant, is placed on the first conveyor belt 31 of the conveyor belt conveyor 30, and is conveyed along the ascending conveyance direction H. When the object to be processed is conveyed to the position of the upstream vibration roller 33, the object to be processed on the first conveyor belt 31 is subjected to strong vibration by the rotation of the upstream vibration roller 33, and has a small specific gravity. The object floats up, and the heavy object to be processed having a high specific gravity sinks. Next, in some cases, the magnetic separator 36 is operated as needed to sort out iron scraps and the like in the workpiece.

When the workpiece M is transported to the position of the downstream vibrating roller 34, the workpiece on the first transport belt 31 is
Micro-vibration is imparted by the rotation of the downstream vibrating roller 34, so that the surface on which the object is placed is smoothed and the rod or the like piercing the object is leveled. in this way,
The object to be processed is placed on the first conveyor belt 31 in a state where the light-weight object to be removed is easily sorted by the sorting device 40 by the vibrations of the upstream vibration roller 33 and the downstream vibration roller 34.

The object conveyed to the position of the sorting device 40 is vibrated by the brush lower vibrating roller 55, and the light object to be processed mainly jumps on the first conveying belt 31, and the brush bristles. 48 is improved.
Then, as described above, the rotation of the rotating brush 41 selectively lifts up the lightweight workpiece, and the discharge chute 8
Sent to 0. In this way, the sorting device 40 performs the sorting process. At this time, since the scraping brush 60 is provided, the light weight object can be jumped up to the region p on the side of the conveying belt loading surface.

The upper layer on the first conveyor belt 31 includes
A state in which almost all of the lightweight workpieces and a part of the heavy workpieces are mixed exists. Most of the lightweight workpieces, in which the heavy workpieces are mixed in a part thereof, slide on the rotating brush 41 and are connected to the quadrant 50a of the lower casing 50.
Is immediately discharged from the first conveyor belt 31 via the first conveyor belt 31.
In other words, the light-weight workpiece once scraped up does not move over a long distance along the outer circumference of the rotating brush 41. As a result, most of the lightweight workpiece is reliably taken out.

Then, the heavy workpiece is rolled down by the inclination and vibration of the inclined separation conveyor 70 with respect to the lightweight workpiece and the heavy workpiece which are lifted up by the rotating brush 41 and the scraping brush 60. Second in vibration
Those conveyed in the ascending direction by the conveyance belt 76 are sorted out as lightweight objects to be processed.

As described above, the heavy workpiece that cannot be lifted up by the rotating brush 41 is discharged from the outlet chute 37 of the conveyor belt conveyor 30. Temporarily rotating brush 41
Even if a heavy workpiece is mixed in the object scraped up by the rotary brush 41, it can be sorted out by the inclined separation conveyor 70 at the subsequent stage, but the light workpiece is not scraped by the rotating brush 41. If it remains, it is discharged as it is, making subsequent sorting impossible. For this reason, by allowing a certain amount of heavy objects to be mixed into the objects scraped up by the rotating brush 41, the sorting processing by the subsequent inclined separation conveyor 70 improves the sorting ability of the entire apparatus. Can be.

As described above, in the sorting conveyor 100 of the present embodiment, the light weight material to be treated in the material to be treated M can be removed at a high separation and recovery rate, and the separation and recovery rate can be greatly improved. A stable selection can be obtained.

Next, an example in which a claw member is provided in the vicinity of the discharge port 54 of the sorting device 40 of the present embodiment will be described. FIG.
It is a front view of the sorting device 40 provided with the claw member. FIG.
As shown in FIG.
A claw member 91 is provided at a boundary portion between them, that is, at the discharge port 54. The claw member 91 is disposed on the outer periphery of the rotation of the rotating brush 41, and the tip 91a
It protrudes inward.

At the discharge port 54, light-weight objects (such as vinyl dust and cloth dust) that are caught on the outer periphery of the rotating brush 41 are caught by the claw members 91 and are removed from the rotating outer periphery of the rotating brush 41. Since the tip of the claw member 91 protrudes into the discharge chute 80, the light-weight workpiece to be caught by the claw member 91 is released from being caught only in the direction in which it falls into the discharge chute 80. That is, it is surely dropped into the discharge chute 80. This allows
It is possible to remove the light-weight object to be caught on the outer periphery of the rotating brush 41.

FIG. 6 is a front view of a sorting device 40 provided with a rotary claw member. As shown in FIG. 6, the claw member 91 has a rotating shaft 9 in the same direction as the rotation center of the rotating brush 41.
3 may be provided with a plurality of radially. In this case, the rotating shaft 93 is driven to rotate in the same direction as the rotating brush 41 by a driving unit (not shown).

In the claw member 91, the plurality of claw members 91 are rotated in the same direction as the rotating brush 41 while being in contact with the outer circumference of the rotating brush 41. That is, the light-weight object to be caught on the outer circumference of the rotating brush 41 is more positively removed by the claw member 91. When the claw member 91 on which the lightweight workpiece is hooked around the rotary brush 41 is rotated and moved into the discharge chute 80, the lightweight workpiece falls into the discharge chute 80. This operation is performed continuously as the claw member 91 rotates.

Next, a second embodiment of the sorting conveyor according to the present invention will be described. 7 is a side view of a magnetic separator used in the second embodiment of the present invention, FIG. 8 is a plan view of FIG. 7, FIG. 9 is a perspective view of the magnetic separator shown in FIG. 7, and FIG. 10 is shown in FIG. FIG. 11 is a cross-sectional view of the magnetic separator in a direction orthogonal to the first conveyor belt. FIG. 11 is an explanatory diagram of an operation of the inclined separation conveyor in which the end pulley is an electromagnetic pulley.

The magnetic separator 101 according to the present embodiment is configured as a modification of the magnetic separator 36 according to the first embodiment.
The configuration is not limited to this, and the magnetic separator 101 of the present embodiment may be used alone. The magnetic separator 101 includes a first conveyor belt 3
A brush belt 103 provided crossing above the
It has a magnet 105 disposed inside the endless circuit of the brush belt 103. Brush belt 10
No. 3 is configured by implanting brush bristles 109 on the outer peripheral surface of the endless flat belt 107. The brush bristles 109 are arranged in a direction orthogonal to the circumferential direction of the endless flat belt 107, and are arranged in a plurality of rows in the outer circumferential direction of the endless flat belt 107. The brush bristles 109 of the brush belt 103 have a length such that the leading ends are slidably contacted with the workpiece on the first transport belt 31. For the brush bristles 109, a hard nylon fiber bundle (in addition, vinyl chloride, polystyrene, or the like) can be preferably used.

As the magnet 105, for example, an electromagnet is used. The magnet 105 is connected to at least the first transport belt 31.
It is assumed that the iron material has a magnetic force capable of adsorbing the iron material conveyed on the outer peripheral lower surface of the brush belt 103. In addition, the brush belt 103 can simultaneously sweep out a part of an object to be transported in the upper layer of the first transport belt 31 from the first transport belt 31 in addition to the iron material moved upward by the magnetic attraction force. ing.

Immediately below the end of the brush belt 103 in the conveying direction of the iron material, an inclined separation conveyor 111 is arranged in an inclined manner. The inclined separating conveyor 111 has the ascending direction as the transport direction. That is, the inclined separation conveyor 111 is driven so as to convey the workpiece swept out of the first conveyor belt 31 by the brush belt 103 in the ascending direction.

Further, a plurality of scraping brushes 113 are provided on both sides of the first conveyor belt 31 at the position where the magnetic separator 101 is provided. In the present embodiment, as shown in FIG. 8, two brushes 1 are provided on the upstream side in the sweeping direction of the brush belt 103 and one scraping brush 1 is provided on the downstream side in the sweeping direction.
13 are provided. The scraping brush 113 has a function of scraping up the processing object conveyed at the side of the loading surface of the first conveyance belt 31 and applying the object to the lower surface of the outer periphery of the brush belt 103.

As shown in FIG. 11, the inclined separation conveyor 111 may be configured such that an electromagnetic pulley 115 is used as a pulley on the end side in the transport direction (in some cases, a pulley on the start end side in the transport direction). The electromagnetic pulley 115 applies a magnetic force to the object to be processed immediately before being discharged from the end of the inclined separation conveyor 111.

Next, the operation of the present embodiment will be described. In a sorting conveyor provided with the magnetic separator 101, a brush belt 103 provided crossing over a first conveyor belt 31 is provided.
Is driven around, the object to be processed in the upper layer of the first transport belt 31 is swept by the brush bristles 109 of the brush belt 103 and is swept out of the first transport belt 31.

At this time, the iron material is attracted to the brush belt 103 and is simultaneously swept out by the magnetic attraction of the magnet 105. The iron material adsorbed on the brush belt 103 is reduced by the magnetic attraction force from the magnet 105 at the end of the brush belt 103, so that the brush belt 103
Is dropped downward from the end in the transport direction. As a result, the workpiece including the iron material is separated from the workpiece transported by the first transport belt 31.

The object to be processed, which has been swept out by the brush belt 103, is fed into the inclined separation conveyor 111. The processing object put into the inclined separation conveyor 111 has the aggregate having a predetermined weight or more reversely rolled down in the conveying direction, and is separated from the lightweight processing object. On the other hand, an iron material such as a track and a light-weight object to be processed are transported in the upward transport direction of the inclined separation conveyor 111. As a result, the aggregate and other foreign matter are separated.

At this time, the object to be transported at the side of the loading surface of the first transport belt 31 is
And is brought into contact with the lower surface of the outer periphery of the brush belt 103. Thereby, the iron material located in the lower layer is dug up at the side of the loading surface of the first conveyor belt 31, and the magnet 1
05 becomes easy to act, and the brush belt 10
3 facilitates adsorption.

When the pulley at the end of the inclined separation conveyor 111 in the transport direction is the electromagnetic pulley 115, the workpiece dropped on the inclined separation conveyor 111 is transported in the ascending transport direction of the inclined separation conveyor 111. In addition, the iron material such as the above-mentioned number line and other lightweight objects to be processed are further separated.

That is, when these foreign substances reach the end of the inclined separation conveyor 111 in the conveying direction, they fall from this end. At this time, the foreign substances 121 such as iron material receiving the magnetic attraction force are removed by the electromagnetic pulley 115. And is conveyed a predetermined distance along the lower surface of the outer periphery of the inclined separation conveyor 111 and then dropped. On the other hand, foreign matter 123 other than iron material
Is parabolically drawn at a position separated by a predetermined distance from the end of the inclined separation conveyor 111 due to inertial force. Further, the aluminum 125 is drawn away from the end of the inclined separation conveyor 111 by a magnetic repulsion, drawing a parabola larger than the foreign matter 123 other than the iron material. As a result, in the inclined separation conveyor 111, the aggregate 1
27, iron material 121, aluminum 125, other foreign matter 123
And four types of separation are possible. The electromagnetic pulley 115
Is the inclined separation conveyor 70 in the first embodiment described above.
And the same operation and effect can be obtained.

Next, a third embodiment of the sorting conveyor according to the present invention will be described. 12 is an overall configuration diagram showing a sorting conveyor according to a third embodiment of the present invention, FIG. 13 is a plan view of FIG. 12, FIG. 14 is an enlarged view of the vicinity of a hopper of the sorting conveyor shown in FIG. 12, and FIG. 12 is an enlarged view of the vicinity of the sieve shown in FIG. 12, FIG. 16 is a plan view of the sieve shown in FIG. 15, and FIG.
It is an enlarged view near the sieve which shows the modification of the sorting conveyor shown in FIG.

The sorting conveyor 131 of the present embodiment includes a receiving hopper 133 into which an object to be processed is charged, a crusher 135 connected to the receiving hopper 133 and crushing the object to be processed into the receiving hopper 133, and a crusher 135. A sieve 137 that separates the crushed workpiece discharged from 135 into a workpiece having a certain size or more and a workpiece having a certain size or less, a crusher connected to the crusher 135 and the crusher 137 A crusher rear-stage conveyor 143 for conveying the object to be processed from 135, a return provided between the sieve 137 and the receiving hopper 133, and an object to be processed having a predetermined size or more selected by the sieve 137 is again conveyed to the hopper. Conveyor 139 and inclined separation provided immediately below the end of return conveyor 139 and arranged in the ascending transport direction It constructed roughly in the Nbeya 141.

The receiving hopper 133 is connected to the sorting conveyor 13.
1, and the object to be processed can be charged from the upper opening. The to-be-processed object from the return conveyor 139 is thrown into the inclined separation conveyor 141 at a substantially central portion in the transport direction. Inclined separation conveyor 1
Reference numeral 41 indicates that an object to be processed having a predetermined weight or more is rolled down on the upstream side in the transport direction and can be put into the crusher 135. On the other hand, an object to be processed having a weight less than the predetermined weight is discharged from the downstream end in the transport direction.

The crusher 135 has a function of crushing, to a size smaller than a predetermined size, an object loaded from the receiving hopper 133 and an object having a predetermined weight or more that has fallen from the inclined separation conveyor 141 to the upstream side in the transport direction. Have. The object to be treated, which has been crushed by the crusher 135 to a size smaller than a predetermined size and discharged from the discharge port of the crusher 135, is conveyed to the sieve 137 by the crusher rear-stage conveyor 143.

The sieve 137 has a mesh 145 having even openings.
Is provided. An object to be processed from the crusher rear conveyor 143 is dropped on the upper surface of the screen 145 of the sieve 137. The dropped object is transported on the net 145, and an object having a size smaller than a predetermined size passes through the net 145 and falls downward. An object to be processed, which has fallen from the net 145 and is smaller than a certain size, is sent to the product conveyor 149.

On the other hand, an object having a predetermined size or more, which does not fall from the net 145 and falls down through the net 145, is dropped to the return conveyor 139. The return conveyor 139 conveys the processing object having a certain size or more to the crusher 135 side again, and the inclined separation conveyor 14.
It is designed to be re-entered into 1.

Next, the operation of the sorting conveyor 131 configured as described above will be described. In the sorting conveyor 131, the processing object put into the receiving hopper 133 is put into the crusher 135.

The object to be processed put into the crusher 135 is crushed to a predetermined size. The processing object crushed by the crusher 135 is conveyed by the crusher rear-stage conveyor 143 and thrown into the sieve 137, and is separated into a processing object having a certain size or more and a processing object having a certain size or less. . The object to be treated having a certain size or more separated by the sieve 137 is put into a return conveyor 139, transported, and put into an inclined separation conveyor 141.
Since the inclined separation conveyor 141 is arranged so that the transport direction is ascending, an object to be processed having a weight equal to or more than a predetermined weight falls down in the transport direction. That is, only the separated objects having a weight equal to or greater than the predetermined weight are crushed by the crusher 1.
35. As a result, the object to be re-introduced into the crusher 135 can be made by removing non-product raw materials such as wood, vinyl, and cloth, which are lightweight objects to be processed.
The object to be processed put into the crusher 135 is
It is crushed again by the crusher 135. Here, by removing the light-weight workpiece before being re-entered into the crusher 135, it is possible to prevent a lightweight workpiece having a cushioning property such as a sponge from being thrown into the crusher 135 and hindering the crushing process. Yes, and sieve 1
The clogging of the 37 nets 145 can be prevented from occurring.

[0096] Then, the object to be processed put into the receiving hopper 133 is circulated between these devices until it becomes smaller than a certain size. On the other hand, the object to be processed, which has become smaller than a certain size, is discharged as an aggregate product 151 from the sieve 137 via the product conveyor 149.

The sorting conveyor 131 according to the third embodiment has been described by way of example in which the inclined separating conveyor 141 is disposed immediately below the end of the return conveyor 139. However, the inclined separating conveyor 141 is not shown in FIG. As shown in the drawing, the processing object inserted between the sieve 137 and the return conveyor 139 and fed from the sieve 137 and rolled back in the transport direction may be fed to the return conveyor 139. .

When the inclined separation conveyor 141 is arranged in this manner, the objects to be processed having a certain size or more separated by the sieve 137 are supplied to the inclined separation conveyor 141. On the other hand, the object to be processed separated by the sieve 137 and having a size smaller than a certain size is transported as a product. An object to be treated having a size equal to or larger than a certain size, which is put into the inclined separation conveyor 141,
Only those having a predetermined weight are rolled down on the upstream side in the transport direction and returned to the return conveyor 139 again. An object to be processed (vinyl, wood piece, cloth, or the like) having a size equal to or larger than a predetermined size and smaller than a predetermined weight is conveyed in the conveying direction of the inclined separation conveyor 141 and is treated as foreign matter. Thus, the object to be processed that has not been crushed to a predetermined size can be crushed again, while large foreign matters other than the product are separated from the product manufacturing line by the inclined separation conveyor 141. Thus, by simply providing the inclined separation conveyor 141 at the subsequent stage of the sieve 137, the sorting conveyor 1 is provided.
The foreign matter removal efficiency can be improved with a simple configuration without making a significant design change to the 31 itself. It should be noted that the inclined separation conveyor 141 of the present embodiment may also be configured to use an electromagnetic pulley as the pulley at the end in the transport direction.

Further, the sorting conveyor 131 is provided with the first
The composite sorting conveyor 161 having a double sorting function may be provided in the preceding stage of the sorting conveyor 100 described in the embodiment and combined with the sorting conveyor 100. That is, in this case, the sorting conveyor 100 is used for the product conveyor 149 shown in FIG.

In the case of such a composite sorting conveyor 161, an object to be processed having a size smaller than a predetermined size separated by the sieve 137 of the sorting conveyor 131 is put into the first conveyor belt 31 and sorted by the sorting conveyor 100. Processing will be performed.

That is, the object to be processed having a size smaller than a certain size separated by the sieve 137 is continuously supplied to the first transport belt 31. Then, the object to be processed which has been sorted to a size smaller than the predetermined size is subjected to foreign matter by the rotating brush 41, the scraping brush 60, the inclined separating conveyor 76, the second vibrating roller 72, and the like provided on the sorting conveyor 100. Removal and separation of the light and heavy objects are performed. As a result, it is possible to select an object to be processed having a fixed size and containing no foreign matter and more suitable for commercialization.

[0102]

As described above in detail, the sorting conveyor according to the present invention uses the rotating brush and the inclined separation conveyor to separate the objects to be processed to some extent by the scraping of the rotating brush. The heavy workpiece is rolled down as it is by the second vibrating roller in the upward transport direction, and the lightweight workpiece is dragged by the movement of the second transport belt in the upward direction. The objects are gradually conveyed, and the heavy objects are sorted upstream of the inclined separation conveyor, and the light objects are sorted downstream, thereby increasing the separation and recovery rate. At this time, most of the light-weight workpieces, in which some heavy workpieces are mixed, are immediately discharged from the first conveyor belt through a guide portion which comes into sliding contact with the rotating brush and connects to the quadrant of the lower casing. Is done. That is, the light-weight workpiece once scraped up does not move along the outer circumference of the rotating brush. As a result, first, most of the lightweight workpiece is reliably taken out. In addition, by a rotating brush that is disposed near the end of the rotating brush and scrapes the object in the rotation locus of the rotating brush,
An object to be processed on the side of the loading surface of the transport belt, which is difficult to slide on the rotating brush, is scraped up and thrown into the rotation locus of the rotating brush, thereby increasing the separation and recovery rate. Furthermore, by providing the fixed brush at the uppermost stream of the inclined separation conveyor, the workpiece to be rolled down to the upstream of the movement of the second conveyor belt of the inclined separation conveyor due to the inclination is such that the rigidity of the fixed brush cannot be completely opposed. The heavy object to be processed rolls down from the upstream side of the second conveyor belt as it is. Further, the light-weight workpiece to be held down by the fixed brush is transported downstream, and is sorted out by being carried out from the downstream side of the second transport belt. In this way, it is possible to more reliably sort the heavy workpiece and the light workpiece. In the second conveyor belt, a small-sized workpiece or a flat workpiece is formed by a driven roller disposed upstream of the workpiece supply position and a vibrating pulley disposed downstream of the workpiece supply position. By giving a sufficient vibration to the, and by appropriately adjusting the vibration frequency, it is possible to sort by holding the small-sized workpiece at that position, and for a flat workpiece, this is a heavy object And can be reliably rolled, and can be prevented from being sorted on the lightweight side.
