Field of the Invention The present invention relates to miscellaneous mixed waste including sticky waste such as garbage left in restaurants from building waste generated during house demolition and waste carried out from homes and offices, compost, bark, etc. The present invention relates to a sieve forming rotor used in a sorting machine for sorting wood chips, earth and sand, crushed stones and the like according to size and the like in a sawmill.

[0002]

2. Description of the Related Art Conventionally, as a sorter of this type, there are a trommel and a vibrating sieve, and the like. Sorting by particle size was performed from small to large. If the material to be sorted is a dry powder mass, it can be efficiently sorted by the sorter as described above.However, the material to be sorted may be wet or wet, such as soil and sticky residue or compost. If the particles are mixed, the screen and the sieve may be clogged, and there is a possibility that the powdery material such as earth and sand cannot be separated on the way.

[0003] The applicant of the present application has proposed a unique sorter that does not cause clogging of sieves even on wet or wet earth and sand, sticky leftovers, and compost (for example, Japanese Patent Application No. Hei 10-26138). See the specification and drawings of the 5-176001 application). As shown in FIG. 6 and FIG. 7, this sorter has a rectangular frame 10 laid on a belt conveyor C2 that carries out small and medium-sized wastes W1 and W2 that have fallen through sieves G between rotors and are sorted out. And rotatable in the same direction (indicated by an arrow R1) from the waste input side to the discharge side of the large waste W3 that has been sorted and left from the waste input side to the discharge side of the large waste W3 that is sorted and left in the same plane. Four rows of rotors 2 bearing
(Of course, more than four rows may be used), these rotors 20 ',..., The rotary drive unit 30, and the discharge unit 15 for the large waste W3 in the rotation direction R1. I have.

In each rotor 20 ', a drive shaft 21 having a square cross section having a gear 33 fixed to one end, and a square hole 25a fitted to the shaft 21 are formed in a boss portion 25b.
5b, a large-diameter rotary body 25 'extending in the radial direction from the periphery of the large-diameter rotary body 25' and a large-diameter rotary body 25 'adjacent in the transport direction have a complicated relationship in the rotor axis direction and the transport direction. Boss portion 25b of a large-diameter rotary body 25 'adjacent in the axial direction so as to form a sieve G having a size of
And a small-diameter ring spacer 28 'interposed between them. The ring portion 25c is integrally formed by protruding from the boss portion 25b within the same rotation work surface region with 12 finger-like projections 26 which are curved backward in the rotation direction. Large diameter rotating body 25 'and small diameter ring spacer 28'
Is formed of hard rubber or plastic.

The protrusion 26 has a hemispherical protrusion 26 on one side.
are protruded, and the other surface is a flat surface.
When the length of the spacer 28 'is changed, the protrusions 26a,.
And the flat surface of the adjacent protruding body 26 changes,
Will change the size of The frame 10 is provided with a conveyor C1 for charging waste such as construction waste material on the upper side of the loading side, and a rampway 15 of a discharging section for discharging large waste W3 is connected on the discharging side. And a rotary drive device 30 disposed outside one of the side walls 11. The rotation drive device 30 includes a variable speed motor 31, a pinion gear 32 with an output shaft thereof, a rotor gear 33 meshing with the pinion gear 32, and an idler gear 34 between adjacent roll gears 33, 33. And the rotor 20 ',
Are all turned in the direction of arrow R1. As described above, in addition to rotating all the rotors 20 at the same speed, a motor 31 is individually attached, or a motor 31 and gears 33 and 34 are provided for each group, and the rotor rotation speed is changed individually for each group. Is also configured.

[0006]

Among the wastes, there are ropes, various strings,
The tape is mixed in, and while being lifted to some extent by the transport wind generated by the rotor 20 'sending the waste during the sorting operation, the waste is sent to the discharge unit 15 together with the large waste W3 while being slightly lifted. The string or the string is not sufficiently lifted and may be wound around the finger-like projection 26. As the winding progresses, the sieve mesh G will be closed,
Operation must be stopped and removed. There is also a demand that furthermore, the cans, heavy rocks, bricks, and the like, which are easy to roll and rebound, be further separated from the large waste W3 at the same time.

[0007] Accordingly, the present invention provides a wide range of sorting from construction waste to sticky items such as food left over from restaurants and compost from farmers, wet and wet earth and sand, crushed stones, bark from sawmills, and wood chips. The material is sorted into at least two types without any clogging in large quantities continuously without clogging. No clogging occurs due to the self-cleaning action, a new opening appears as a sieve, and processing capacity Large, vibration-free, low-noise, simple installation foundation work, and used for a simple structure sorting machine, and can be sent out in the rotor rotation direction without causing rope, string, or tape wrapping. It is intended to provide a rotor.

[0008]

In order to attain the above object, according to a first aspect of the present invention, there is provided a rotor for a sorter, wherein sorted objects having different sizes are mixed and supplied from above by a loading means. A rotor assembly comprising a plurality of rotors arranged such that the rotor axes are rotatable in parallel with each other in the frame from the supply side to the discharge side of the large-sized material remaining after being sorted, and displacing the rotor from the supply side to the discharge side. And a rotary drive means for rotating and driving in the same direction so as to feed the object to be sorted.The rotor used in the sorting machine for sieving the object to be sorted while being conveyed from the supply side to the discharge side. In the rotor arrangement direction from the supply side to the discharge side, adjacent ones are interdigitated with each other at intervals and form sieves at intervals. The large-diameter portion and the small-diameter portion are provided in such a manner that a plurality of large-diameter portions and a plurality of small-diameter portions are alternately shifted from each other in the axial direction of the rotor. A connecting plate formed between the protruding bodies so as to connect the protruding bodies to each other. It is characterized by being installed in the middle of the area.

Preferably, the projecting body is curved backward with respect to the rotor rotation direction. In addition, as described in claim 3, the small-diameter portion is configured to provide an uneven portion on a peripheral surface thereof. Further, the rotor assembly is tilted from the horizontal state to the tilted state via the frame by the expansion and contraction means. In addition, as described in claim 5, the rotor assembly has at least one approach portion in the middle.

[0010]

As described above, in the rotor of the sorter having the structure described in claim 1, a plurality of rotors are arranged horizontally and in parallel from the input side of the object to be processed to the discharge side of the large material remaining after being sorted. The large-diameter portion and the small-diameter portion of the rotor that are adjacent to each other so that the front and rear adjacent ones do not hit each other are in a state of being intertwined with each other, forming a sieve between them, and The small and small objects in the container are sorted by dropping from the sieves. Since the plurality of rotors are driven to rotate in the same direction from the input side to the discharge side, a lump is beaten and unraveled by the protrusion of the large diameter portion to promote sorting, and does not pass through a sieve. Large pieces such as stones, concrete pieces, bottles, cans, wood, plastic bottles, metal pieces, plates, etc. remaining on the rotor assembly are selectively conveyed to the discharge side.
Since the sieve is formed between the large diameter and small diameter parts of the adjacent rotating rotor, it is always automatically cleaned, and it is possible to sort out sticky or damp or wet objects without clogging. can do.

[0011] Since the sorting operation is carried out by transporting and untangling the workpiece only by rotating the rotor, there is almost no generation of vibration and noise, and a large number of sorting processes can be performed. I can do it. Also, the operating part is very easy to maintain due to the simple configuration of only the rotor and its rotary drive. Even if ropes, strings, tapes, etc. are mixed in the workpiece, the rotating rotor can be lifted, especially if it is light due to the transport wind from the supply side to the discharge side caused by the large diameter projection on the rotor assembly. Then, even heavy objects are sorted and conveyed to the discharge section together with large objects while being passed on by the protruding bodies. During transportation, ropes, cords, and tapes are protruded by connecting plates that are extended from the top end of each projection to the middle of the front surface of the next projection while securing the support surface of the sorting object on the front surface of the projection. Winding around the body can be reliably prevented. In addition, during rotation, a wind flowing above the rotor projection itself is generated on the rotor assembly, so that a light thing such as a radio cassette tape, a video cassette tape, or a nylon string can be floated and discharged.

In the rotor of the sorting machine according to the second aspect, the ability to support the sorting object curved backward is increased.
Even if the number of rotations of the rotor is increased, it is possible to take over from the supply side to the discharge side while appropriately breaking up the lump without hitting and sorting the objects to be sorted without darkness, thereby increasing the throughput. In the rotor of the sorter according to the third aspect, the small-diameter portion is provided with an uneven portion on a peripheral surface thereof, and can generate a conveying wind.

According to a fourth aspect of the present invention, the rotor assembly is tilted by the expansion and contraction means, and in the horizontal state, the objects to be sorted are sorted into objects that pass only through the sieve and that do not pass through the sieve in the horizontal state. In this method, the material remaining on the rotor assembly without passing through the sieve can be more easily rolled, and can be separated into a heavy material and a lighter material that is less likely to roll and a non-repellent material. When the degree of inclination is increased, the weight selection branching point is shifted to a lighter side, and more weight is sorted to the heavy object side. In the rotor of the sorting machine according to the fifth aspect, the sorting object is repeatedly inverted at the place where it approaches, and stays for a while, and the thing entered into a lump, bag, container, or the like is inverted and unraveled or scattered. That is, the attached matter is separated, and the overlap is separated to promote the sorting, thereby increasing the sorting accuracy. Heavy and resilient objects have large jumping and are quickly released and separated quickly, while light and low-repulsion objects have small jumping and jump many times.

Further, the housing 60 is provided with the approaching portion 4 at the center of the assembly 4A.
The passage 61 is bent in a mountain shape corresponding to C, and a first nozzle 67 that blows out a blow-up air flow A1 that assists the conveyance of paper, tape, and a string, among the lightweight objects W5, is provided at the lower end. Further, each of the intermediate portions has a second nozzle 68 that blows out the airflow A2 that blows out toward the approaching portion 4C to unwind a book or the like that is overlapped or clumped and presses against the approaching portion 4C. To achieve the horizontal state with the inclination angle α = 0, the expansion / contraction means 19A is contracted, and the expansion / contraction means base 19C is lowered by the jack means 19B. At this time, the sub-housing 65 is appropriately removed.

The rotor assembly 4A has a central approaching portion 4C, but is basically the same as that of the conventional example. The square rotor 20 constituting this assembly 4A is shown in FIGS. As described above, a drive shaft 21 having a square cross section having a gear 33 fixed to one end, and a square hole 25a fitted to the shaft 21 are formed in a boss 25b, and a ring body is formed radially from the periphery of the boss 25b.

The large-diameter portion 25 and the small-diameter portion 28 are integrally formed of hard rubber or plastic.
The annular body portion 25c is formed between the boss portion 25b and, for example, 12 finger-like projections 26 radially projecting rearward in the rotor rotation direction and the finger-like projections 26 and the adjacent projections 26, 26. And a connecting plate 27 extending from the top end to the middle of the front surface of the rear protruding body. Therefore, even if a little heavy rope, string, tape, or the like is mixed in the waste W to be blown up by the conveying wind generated by the rotating rotor 20 or the blown-up airflow A1, they are wound around the protruding body 26. , Which are successively inherited by the protrusions 26,... And are selectively conveyed upward together with the lightweight object W5. Small diameter part 2
An uneven portion that generates a conveying wind is also provided on the peripheral surface of the roller 8.

.. Are projected, and the other surface is a flat surface. When the length of the small diameter portion 28 is changed, the distance between the projections 26a,... And the flat surface of the adjacent protrusion 26 changes, and the size of the sieve mesh G changes.

The rotor rotation driving device 30 is also basically the same as the conventional one, and includes a variable speed motor, a pinion gear with an output shaft thereof, a gear with a rotor 33 meshing with the pinion gear, and a gear with an adjacent roll 33. , 33 and the idler gear 34 so that all of the rotors 20,... Rotate in the direction of arrow R1. (Of course,
The rotor 20 can also be partially reversed by another drive. As described above, in addition to rotating all the rotors 20 at the same speed, a motor 31 is individually provided, or motors and gears 33 and 34 are provided for each group, and the rotor rotation speed is individually changed for each group. Is also configured. Each rotor 20 has a bearing 11a on the frame wall 11 together with the gear 33.
Supported rotatably via the idler gear 34
Is rotatably mounted on the frame 11.

The frame 11 basically has a tilted state, but may be in a horizontal state as described above. Specifically, the inclined frame 11A includes front and rear identical inclined angle portions 11B, 11B, and a mountain-shaped portion 1 rising between them.
1C, on which the rotors 20,... Are mounted together with the gears 33, 34 of the rotary drive 30 via bearings 11a. In this embodiment, the mixed waste W charged on the lower inclined portion 4B is rotated by the rotating rotor 20,.
.. the heavy object W4, which is released when hit by the repellent material and rolls, falls down to the discharge opening 62 while jumping, and the light-weight material W5 which is hard to roll and is non-repulsive is the rotor 20,
Are released and dispersed while being conveyed while being jumped slightly upward by the rotation of..., A sieve G formed between the left and right adjacent protrusions 26 and between the tip of the protrusion 26 and the small diameter portion 28. And small and small objects W1, W2

In the approaching part 4C, the remaining lump of piled-up or attached matter or waste left in bags, containers, and the like is inverted as indicated by an arrow R2, and the lump and overlap are further unraveled and dispersed. And the waste in the container are scattered to promote the sorting of the small and small objects W1 and W2 (the sorted small and small objects W1 and W2 are carried out by the conveyor C2). The mixed waste W is successively unraveled by the rotors 20,.
Since it falls down below the sieve mesh G or is conveyed upward, it will be continuously and efficiently sorted in a large amount, and the sorting ability and the sorting accuracy will be improved. The machine length can be shorter than that without the part 4C.

The air flowing upward during operation is generated on the rotor assembly 4A by the protruding body 26 itself of the rotating rotor 20, the protrusions 26a, 26a on the side surface thereof, the protruding portion of the small diameter portion, and the like. With the addition of the airflow A1, light objects such as radio cassette tapes, video cassette tapes, nylon strings, etc. can be lifted without winding and discharged from the opening 63. A bundle of a slightly heavy string or rope is successively inherited and discharged via the upper end while being prevented from being wound by the connecting plate 27 by the finger-like projection 26 and the projection 26a. Further, the projection 2 which rotates even if wastes W and compost having a high water content are mixed in the waste W.
New sieves G are formed one after another by the 6, the projections 26a and the small diameter portions 28, and can be dropped downward without causing clogging. By using this, the compost can be sieved. Furthermore, it is hard to cause clogging and breakage, etc. It is easy to maintain with a simple structure of installation work, and it can continuously sort large quantities of construction waste, household waste, office waste, restaurant leftovers, etc. into three types. .

This sorter 1 separates and sorts not only the above-mentioned construction waste and household waste, but also separates and separates vinyl strings and vinyl sheets from which magazines and newspapers are bundled, and further shakes dirt and foreign matter from magazines and newspapers. It is suitable for dropping, and sorts magazines and newspapers as heavy objects W4, strings and sheets as lightweight objects W5, and soil and foreign matters as minute objects W1. In particular, in the approaching section 4C, it is possible to separate the strings or sheets sandwiched between the overlapped books or newspapers while reversing the strings or sheets. Inclination angle α
The rotation speed of the rotor 20 is set such that magazines and newspapers slide down on the rotor 20. The approaching portion 4C can be formed not only so as to protrude the plurality of rotors 20 in a mountain shape but also to be arranged in a trapezoidal shape,
When the rotation speed is increased, the reversal conveyance becomes stronger from the reversal stay. Further, a mountain shape and a trapezoidal shape can be mixed. The rotor assembly 4A is divided into a plurality of blocks according to the rotation speed from high speed to low speed, and the sieves G are configured to be relatively small to large, and the size of the sieves G is actually changed by changing the length of the small diameter portion 28. The sieving of small and medium can be further divided into several types.

[0022]

As described above, according to the rotor of the sorter having the structure according to the first aspect of the present invention, a wide range of materials from construction waste to restaurant leftovers and wet or wet soil is obtained. Even large quantities of sorted waste such as mixed waste and compost from farmers can be sorted in large quantities into at least two different sizes, and light ropes, strings and tapes are rotated so that they do not wind around the rolls. Can be lifted and sent out by the wind generated by the rotor, and even a slightly heavy rope or string can be selectively conveyed by the upper bearing surface of the irregularities of the large diameter part while securely preventing it from winding around the protruding body with the connecting plate. . The sieve is formed by the combination of adjacent large-diameter and small-diameter parts of the rotating rotor, so there is no vibration, low noise, easy installation foundation work, and fewer components and maintenance. Is also easy.

According to the rotor of the second aspect of the present invention, the ability to support the object to be sorted which is curved rearward is increased, so that the object to be sorted can be properly applied without scattering the object without any darkness even when the rotation speed of the rotor is increased. The lumps can be passed from the supply side to the discharge side while the lumps are being unwound, and the throughput can be increased. In the rotor of the sorter according to the third aspect, the small-diameter portion is provided with an uneven portion on a peripheral surface thereof, and can generate a conveying wind.

According to a fourth aspect of the present invention, the rotor assembly is tilted by the expansion and contraction means, and in the horizontal state, the objects to be sorted are separated into those that only pass through the sieve and those that do not pass through in the horizontal state, and those that are not inclined in the horizontal state. Objects remaining on the rotor assembly without passing through the sieve can be more easily rolled and resilience can be selected into heavy ones and lighter ones which are hard to roll and non-repulsive ones. When the degree of inclination is increased, the weight selection branching point is shifted to a lighter side, and more weight is sorted to the heavy object side.
In the rotor of the sorting machine according to the fifth aspect, the sorting object is repeatedly inverted at the approaching portion, so that the objects contained in the lump, the bag, the container, and the like are unraveled or scattered during the inversion, and the adhering material is removed. Are separated, and the overlapped objects are separated to promote the sorting, so that the sorting accuracy can be improved.
