Description

  The present invention relates to an aligning feeder that performs continuous supply (injection) or a group of conveying objects (solid materials) having different shapes and sizes, etc., in a predetermined manner (sorting).

  The applicant of the present application acquires the shape information, the color information color, and the texture information for each waste from the image information obtained for each waste regarding the waste that is the processing target in Patent Document 1 that is the application of the present application, A waste material determination method and a material determination device for determining a material for each waste based on such information have been proposed.

  In a waste treatment system using such a waste material judgment method and a material judgment device, various wastes to be mixed and mixed are separated and disposed of according to the material judgment result of waste. In order to accurately determine the material quality of the waste, it is necessary to arrange the wastes to be mixed and arranged in an independent state and transport them to the waste material determination device.

  That is, for example, if a plurality of adjacent wastes are in contact with each other or overlap, it is not possible to accurately determine the material of each waste, and the waste is sorted by material and sent to post-processing. There is a risk that it will not be possible.

Conventionally, for example, a vibrating screen as described in Patent Document 2 is known as a technique for separating waste.
This type of equipment classifies (classifies) the processing object (waste, etc.) by vibrating the sieve (mesh), and has different mesh sizes with respect to the conveying direction of the processing object (waste, etc.) By arranging a plurality of (particle diameter) meshes (or by exchanging with meshes having different mesh sizes), the particles can be divided for each particle diameter (see, for example, FIG. 9).

Further, as described in Patent Document 3, there is known an alignment feeder that can be aligned and transferred on a moving path by vibrating a processing object.
This type of device is a vibration feeder that conveys a processing object by vibration and has a function of aligning the processing object. The processing object is stored in a container such as a bowl and then vibrated. In order to convey the processing object in a predetermined direction, the conveyance direction of the processing object is determined by adjusting the vibration direction and frequency, and a guide that takes into account the shape of the processing object is provided and dropped from there. It is configured so that it can be aligned (see, for example, FIG. 10).

JP 2010-38689 A Utility Model Registration No. 3026700 Japanese Patent Laid-Open No. 9-2642

  However, since the vibrating screen as described in Patent Document 2 has a structure in which an object cannot be conveyed after sizing, in order to align and convey the object after sizing In addition, it is necessary to separately provide a conveyor device such as a belt conveyor and a vibration feeder, and a device for aligning the objects in a predetermined manner, which may increase the cost and make the structure complicated, and causes a problem of installation space. There is the actual situation.

  In addition, when sizing using a mesh, it is difficult to suppress the occurrence of clogging. For example, when a relatively heavy object such as industrial waste is continuously charged, for example, To check for clogging, it is necessary for humans to constantly monitor, and once clogging occurs, it is necessary to stop the device and perform a relatively large and time-consuming removal work. There is a fact that it is difficult to increase efficiency.

  The alignment feeder as described in Patent Document 3 generally performs flow alignment with objects having the same shape and size (parts and the like) as an object. For example, the shape and size of industrial waste, In the case where a mixture of various objects (solid materials) having different specific gravities is used, there are the following situations.

  That is, since there is a possibility that the conveyance speed (movement speed) varies depending on the difference in objects, for example, an object (solid substance) with a high movement speed catches up with an object (solid substance) with a low movement speed and overlaps. There is a situation that it is not possible to arrange well in order to get over.

  For example, in the case of a concrete lump, in the experiment, a phenomenon was observed in which a lump having a large size has a relatively higher moving speed than a lump having a small size. The phenomenon may vary depending on the vibration direction, amplitude, and the like.

  Therefore, in the apparatus as described in Patent Document 3, the processing object is sequentially transported with an interval capable of realizing highly accurate determination with respect to the waste material determination apparatus as described in Patent Document 1. There is a high possibility that it will not be possible.

  The present invention has been made in view of the above-described circumstances, and is configured and transported while sorting the transport target objects in a predetermined manner without causing clogging or the like in the middle of the transport path while having a simple and low-cost configuration. An object of the present invention is to provide an alignment feeder (alignment conveyance device) that can perform the above-described operation.

For this reason, the present invention
An alignment feeder capable of aligning and conveying the supplied conveyance object using vibration,
The conveyance object to be supplied is an oscillating inclined surface that is at least inclined in a direction orthogonal to the conveyance direction, and on the inclined surface , the conveyance object has a conveyance force in the conveyance direction, and While acting the force of gravity fall component by the inclined surface,

  In the present invention, the degree of separation can be adjusted by adjusting the degree of regulation of the fall on the inclined surface due to the force of the gravity drop component according to the degree of protrusion from the inclined surface of the bank body portion. .

  In the present invention, a portion having a smaller amount of protrusion from the inclined surface than other portions may be provided in the middle portion of the bank body in the conveying direction.

  In the present invention, a guide may be provided that abuts against an object that is larger than a predetermined size among objects to be dropped that are regulated by the levee body part and falls from the dam body part.

  In this invention, the said bank body part can be arranged in multiple steps | paragraphs in the conveyance direction width direction.

  In the present invention, a gap between the lower end of the partition plate and the upper surface of the inclined surface may be increased as it proceeds to the downstream side in the transport direction.

  A plurality of the partition plates may be provided in the transport direction.

  In the present invention, the upstream end of the partition plate on the downstream side in the transport direction may be offset to the lower side in the falling direction of the inclined surface with respect to the downstream end of the partition plate on the upstream side in the transport direction. .

  In the present invention, the partition plate may be arranged in a plurality of stages in the width direction of the conveyance direction.

  The present invention provides an alignment feeder (alignment conveyance device) that can be arranged and conveyed while being sorted in a predetermined manner without causing clogging or the like in the middle of the conveyance path while having a simple and low-cost configuration.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the embodiments described below.

<First Embodiment>
The alignment feeder 100 according to the present embodiment is used in a sorting system for industrial waste or the like as shown in FIG.
The sorting system according to the present embodiment generally operates as follows.

(1) Step 1
In the most upstream hopper 1 shown in FIG. 1, waste, which is an example of an object to be conveyed in an aligned manner, is charged.
In addition, waste is crushed and crushed into concrete using a double-arm manipulator equipped with a self-propelled hydraulic excavator, gripper, etc. Etc. to adjust to a predetermined size.
The waste includes concrete glass, metal such as iron and aluminum, resin such as plastic, and wood.

(2) Step 2
The waste thrown into the hopper 1 is crushed by the vibration feeder 2 so as to be supplied in a predetermined amount to the downstream process.

(3) Step 3
In the vibration screen 3 in the downstream process of the vibration feeder 2, waste of a nonstandard (small diameter) size that has passed through the interval between the comb blades by a multi-row comb is dropped and excluded. For example, the upstream half of the vibrating screen 3 has a flat plate shape, and the waste supplied from the vibrating feeder 2 is dispersed to remove the overlap between the wastes to some extent. The downstream half is formed in the aforementioned comb shape.

(4) Step 4
Among solid wastes, solids (irons and the like) having predetermined magnetism are removed on the vibrating screen 3 by a magnetic separator 4 that removes magnetic solids (irons and the like) using magnetic attraction force. . The magnetic solids (irons and the like) removed by the magnetic separator 4 are collected at a predetermined iron gathering place by another route.
However, not all irons are removed by the magnetic separator 4, and iron pieces with a small area may not be removed. Therefore, the subsequent material determination unit 6 also identifies iron, and when it is identified as iron, the scraping device 7 scrapes it out. That is, “iron” may be included in the subsequent waste.

(5) Step 5
The waste of a predetermined size from which magnetic solids (such as irons) are removed is separated into a predetermined size by the vibrating screen 3 and the sizing / sorting unit 5 (alignment feeder according to the present invention) is arranged and conveyed. 100).
Details of the sizing / aligning portion 5 will be described later.

(6) Step 6
The individual wastes that are aligned in a predetermined manner by the sizing / arranging unit 5 and are sequentially conveyed in an independent state at a predetermined interval are transferred to the belt conveyor 6A disposed near the outlet of the sizing / arranging unit 5. It is placed and carried into the material determination unit 6 based on waste image information.
For example, the material determination unit 6 can use the waste material determination device described in Patent Document 1 described above, but other material determination devices can also be used.
For example, the material determination unit 6 acquires image information for each individual waste conveyed on the belt conveyor 6A, and based on the acquired image information, shape information, color information color, texture for each waste. Information is acquired and the material is determined for each waste based on the information.

(7) Step 7
Based on the result of waste material judgment in the material judgment unit 6, the scraping device 7 scrapes waste other than concrete (resin such as iron, aluminum, plastic, wood, etc.) from the belt conveyor 6A, apron conveyor, etc. It transfers to the relay conveyor 8 which consists of.
For example, the scraping device 7 uses a flap or a hand-like element driven by an actuator such as an air cylinder (or a gear drive, etc.) to discard individual materials other than concrete based on the material determination result of the waste in the material determination unit 6. Objects can be configured to be individually scraped (or extruded) onto the relay conveyor 8.

(8) Step 8
Waste other than concrete scraped by the scraping device 7 (resin such as aluminum and plastic, wood, etc.) is conveyed by the relay conveyor 8 to the material determination unit 9 similar to the material determination unit 6.
The relay conveyor 8 is provided with a conveyor stand that protrudes on the belt conveyor in a predetermined manner, and is separated by the conveyor stand so that waste can be individually conveyed without approaching more than a predetermined distance. It is also possible to transport objects in the height direction.

(9) Step 9
The relay conveyor 8 freely drops the waste at the most downstream side and sequentially puts the waste into the chute 9A. The waste that has passed through the chute 9A is placed on the belt conveyor 9B.
The waste on the belt conveyor 9 </ b> B is carried into the material determination unit 9, and the material is determined for each waste by the same method as the material determination unit 6.

(10) Step 10
Based on the result of waste material judgment in the material judgment unit 9, after sorting out resin such as iron, aluminum and plastic, wood, and other waste for each material, the scraping device 10 disposes the waste on the belt conveyor 9B. Although scraped from above, the scraping direction and timing can be controlled so that each waste can be collected in the storage container 11 corresponding to the material of the waste to be scraped. The scraping device 10 can have the same configuration as the scraping device 7.

  According to the industrial waste sorting system according to the present embodiment having such a configuration, waste (concrete, iron, aluminum, plastic resin, wood, etc.) generated by building demolition work, etc. is automatically It is possible to select and collect materials according to the quality of the materials, and the waste that has been accurately selected can be used for post-processing according to the materials, which contributes to the realization of efficient post-processing work, etc. it can.

  Here, the alignment feeder 100 which is an example of the sizing / aligning unit 5 according to the present embodiment will be described.

  As shown in FIG. 2, waste, which is an example of an object to be aligned and transported, is continuously input from the input unit 110 to the alignment feeder 100 (bank body type) according to the present embodiment, for example.

  Specifically, for example, wastes (concrete glass, non-magnetic metal, plastic resin, wood, etc.) adjusted to a predetermined size in the pretreatment are sequentially dropped from the vibrating screen 3 to the input unit 110. Input (supply).

  Various wastes dropped from the loading unit 110 are guided to the conveyance unit 120 functioning as a vibration feeder. First, the waste dropped from the loading unit 110 is a cross-sectional view of the recess 120A provided in the conveyance unit 120. 2 collides with the L-shaped long-side bottom 120B and the like, toward the short-side bottom 120C side having a substantially L-shaped cross-section, and further to the left side in FIG. Guided to 122A.

Note that both sides in the transport direction of the transport unit 120 are defined by a left side wall 140 and a right side wall 150 extending in the transport direction with a predetermined height.
Further, the whole shown in FIG. 2 is vibrated through an electric motor or the like with a predetermined amplitude at a predetermined cycle.

  Here, since the conveyance part 120 functions as a vibration feeder, the conveyance force resulting from the energy by the free fall which remains and the conveyance force provided by a vibration act on the thrown-in waste.

Moreover, the conveyance part 120 has the inclined surface 122 where the right direction of FIG. 2 fell.
Therefore, as shown in FIGS. 2 and 3, the force (GF) of the gravity component (falling direction component) traveling rightward in FIG. 2 acts on the waste on the inclined surface 122 of the transport unit 120. Therefore, on the inclined surface 122, the waste is transported obliquely with respect to the transport direction by the transport force (CF) due to vibration and the force (GF) of the gravity component (fall direction component). (RF) acts.

  In addition, as shown in FIG. 3, the inclined surface 122 is inclined in the advancing direction so that the downstream side in the transport direction is slightly lower than the upstream side (forward tilt) (when the transport force of the vibration feeder in the transport direction is strong, etc.) Can be disposed at an inclination (reverse inclination) opposite to this), and by adjusting the angle of the advancing direction inclination (forward inclination, backward inclination), for example, desired conveyance Fine adjustment is possible to obtain speed. The conveyance speed can be adjusted by adjusting the excitation force, the vibration frequency, or a combination thereof.

  Here, as shown in FIGS. 2 and 3, the dam body 121 includes a concave portion (conveyance path) 122 </ b> B on the right side in FIG. 2 along the inclined surface 122 by the force of gravity component (falling direction component). It protrudes from the inclined surface 122 in a predetermined manner so as to function so as to restrict rolling down.

  Comparison between the waste regulated by the ridgeline portion 121A of the levee body portion 121 and guided and conveyed by the concave portion 122A on the left side in FIG. 2 that protrudes from the ridgeline portion 121A of the levee body portion 121 to the right side in FIG. A large-sized (large-diameter) waste gets over the ridgeline portion 121A and falls to the concave portion 122B on the right side in FIG. 2 due to vibration or the like, and is guided to the large-diameter lane 130B of the discharge unit 130. .

  On the other hand, the relatively small (small-diameter) waste is regulated by the levee body 121 and is transported in the recess 122A on the left side in FIG. Guided to a small-diameter lane (conveyance path) 130A of the section 130.

  As shown in FIG. 2 and FIG. 3, the ridgeline portion 121A of the levee body portion 121 is once changed to a ridgeline portion 121B having a small overhang in the lateral direction of the conveyance direction on the downstream side in the conveyance direction, and then again the ridgeline portion. It is configured to have a ridge line portion 121C having an overhang similar to that of the portion 121A.

  Therefore, although the waste that has been transported without falling to the concave portion 122B side over the first ridge line portion 121A is moved to the ridge line portion 121B having a smaller overhang than the ridge line portion 121A, although it is a relatively large size, Since it is easy to get over the ridgeline portion 121B, it is dropped into the concave portion 122B on the right side in FIG.

  When the waste moves from the ridge line portion 121A to the ridge line portion 121B having a small overhang, the center of gravity of the object to be conveyed due to vibration becomes unstable. Thus, it is possible to easily drop a relatively large size waste into the concave portion 122B on the right side in FIG.

  Furthermore, although it is a comparatively large size, the waste that has protruded from the ridge line portion 121B to the right side in FIG. 2 but has been transported along the concave portion 122A without falling to the concave portion 122B side is separated from the ridge line portion 121C and the ridge line. The protruding portion collides with the stepped portion X with respect to the portion 121B, and the collision is urged to drop to the concave portion 122B on the right side in FIG. That is, the stepped portion X contributes to making it easier to drop a relatively large size waste into the concave portion 122B on the right side in FIG.

  Further, in the present embodiment, a guide 123 is further provided in the present embodiment, assuming that the waste having a target size cannot be dropped to the concave portion 122B side in the dam body portion 121.

  As shown in FIGS. 2, 3, and 4, the guide 123 is located above the conveyance path along the concave portion 122A on the left side in FIG. 2 from the ridgeline portion 121A (121B, 121C) and from the right wall 140 toward the concave portion 122A. A predetermined amount protrudes. The shape, mounting height, protrusion amount, and the like of the guide 123 can be appropriately changed in accordance with the size of the waste to be dropped into the concave portion 122B on the right side in FIG.

  According to such a guide 123, as shown in FIG. 4, only a relatively tall waste that interferes with the guide 123 is guided to the recess 122B.

  The guide 123 is not provided on the upstream side, since the vicinity of the input unit 110 is immediately after the input, and the waste is in a relatively dense state. This is because if the movement in the direction is restricted, there is a risk of clogging and the like due to the surrounding small waste.

  That is, the waste is sized by the dam body portion 121 on the relatively upstream side, and the sizing by the guide 123 is performed at a predetermined interval between adjacent wastes, thereby reliably preventing clogging and the like from occurring. This makes it possible to perform highly accurate sizing.

  By the way, since the small-sized waste is hardly affected by the amount of overhang of the levee body 121, the waste basically travels along the conveyance path along the concave portion 122A on the left side in FIG. For example, if the ridge line portion 121A is omitted and the ridge line portion 121B has a small bulge amount from the beginning due to “unexpected movement” such as “bounce” due to interference or vibration of the ridge line, the ridge line portion 121B has a bulge amount (the height of the levee body in the experiment). In the case of (projection amount) 18 mm), a case of falling to the right concave portion 122B side in FIG. 2 was observed (experimental conditions: frequency 20 Hz, amplitude 5.2 mm, vibration direction: diagonally upward in the traveling direction, inclination in the traveling direction) : Downward 5 degrees, inclined plate angle: 15 degrees).

  Since such a small-sized waste is not originally desired to fall to the concave portion 122B side, in this embodiment, the amount of overhang is initially set as a stable section so that it does not fall even if there is an “unexpected movement”. A section of a large ridge line portion 121A is provided to prevent an unexpected fall of a small-sized waste.

  Further, the small-diameter lane 130A is formed in a slope shape having a height that increases toward the upstream side in the transport direction, thereby reducing the size from the end 122C of the transport path along the concave portion 122A on the left side in FIG. When the waste falls to the small-diameter lane 130A, it is prevented from overlapping with adjacent waste due to “bounce” or the like, or jumping to the large-diameter lane 130B.

  The present inventors conducted an experiment of separating (sizing) a construction waste (mainly concrete lump) having a particle size of about 40 to 300 mm with a particle size of about 100 mm as a boundary. The levee body section (121A section) is about 35mm in height (projection amount) about 600mm in length, and the A section (section 121B) is about 18mm in height (projection amount) about 150mm in length. The separation rate was the highest when the rear bank part (section 121C) was about 35 mm in height (projection amount) and about 130 mm in length.

  In addition, although the amount of protrusion of the levee body part 121 was made into two steps, the section of the ridgeline portion 121A (121C) and the section of the ridgeline portion 121B, it is not limited to this, and more stages (3 It is also possible to provide multiple stages).

  However, depending on the use conditions, the required degree, etc., it is possible to omit the ridge line portion 121B having a small overhang amount and adopt a structure having a common overhang amount over the entire dam body portion 121.

  The waste distributed to the small-diameter lane 130A and the large-diameter lane 130B is conveyed toward the downstream side in the conveyance direction by vibration.

  As described above, according to the present embodiment, when wastes having different shapes and sizes are introduced, the wastes are transported in a predetermined transport direction by the energy of dropping or the excitation force of the vibration feeder. As shown in FIG. 2, FIG. 3, etc., the force of the drop direction component acts by the inclined surface 122 constituting a part of the transport surface.

  And in this Embodiment, the fall by the force of this drop direction component is controlled by the bank body part 121, and about the waste of comparatively small size, it goes toward the conveyance direction downstream along the recessed part 122A. It can be transported and transported along the small diameter lane (conveyance path) 130A downstream in the transport direction.

  On the other hand, waste of a relatively large size can be moved over the ridgeline portions 121A, 121B, 121C of the levee body portion 121 by the force of the dropping direction component and dropped into the concave portion 121B on the right side in FIG. Thus, it can be transported along the large diameter lane 130B to the downstream side in the transport direction.

  In each lane, the respective wastes are transported side by side along the transport direction.

  According to the present embodiment, since the particles are sized according to the size, it is possible to prevent entry into the lower side of the adjacent waste in each lane. Can be transported in an aligned state.

  That is, according to the present embodiment, it is possible to classify wastes having different shapes and sizes, and transport the sorted wastes in alignment with the transport path corresponding to the particle diameter.

  Further, in this embodiment, since waste does not clog up in the middle of the conveyance path and cause a phenomenon such as clogging, there is no need for a relatively large and time-consuming removal operation, and disposal For example, automatic operation is possible because there is no need for humans to constantly monitor the occurrence of clogging, for example, to check the occurrence of clogging, which greatly improves work efficiency compared to conventional devices. Can be increased.

  In addition, a phenomenon in which wastes adjacent to each other in each of the small-diameter lane 130A and the large-diameter lane 130B come into close contact with each other in the transport direction is also assumed. With such a configuration, the waste can be sent to the material determination unit 6 with a predetermined interval in the transport direction so that the material determination unit 6 in the subsequent process can perform the material determination with high accuracy. It has become.

That is, the belt conveyor 6A is connected to the downstream side of the small diameter lane 130A and the large diameter lane 130B.
Thereby, a relatively small size waste and a relatively large size waste are supplied from each lane onto the belt conveyor 6A (by dropping or the like), but the relatively small size waste and the relatively large size are supplied. Is disposed so as to be distinguishable in the width direction of the belt conveyor 6A.

  In addition, by setting the conveyance speed of the belt conveyor 6A higher than the conveyance speed due to the vibration of the alignment feeder 100 (small diameter lane 130A, large diameter lane 130B), even if the waste is close to the conveyance speed Since the interval between the adjacent wastes can be widened by the speed difference, the interval between the wastes in the transport direction of the belt conveyor 6A can be made predetermined.

  Accordingly, the material determination unit 6 can individually determine the materials of the wastes supplied from the small-diameter lane 130A and determine the material of each waste with high accuracy, and similarly, the waste supplied from the large-diameter lane 130B. The material of each waste can be determined with high accuracy by individualizing the material.

  By the way, in this embodiment, regarding the belt conveyor 6A, the waste carried out from the small-diameter lane 130A and the waste carried out from the large-diameter lane 130B are placed on a common belt. It can be set as the structure provided with an independent belt conveyor corresponding to each lane. Thereby, since the conveyance speed of a belt conveyor can be set independently corresponding to each lane, it is useful when, for example, it is desired to further improve the material determination accuracy of the material determination unit 6.

  In the present embodiment, a description has been given of a configuration example in which the bank body part 121 is provided in only one row in the width direction in the waste transport direction, but the present invention is not limited to this, and the bank body part 121 is provided. Are provided in a plurality of rows (multi-stages) in the width direction of the conveyance direction, and the plurality of stages of conveyance paths are provided by appropriately adjusting the amount of overhang of each levee body part, so that not only large diameters and small diameters are further provided. It is also possible to adopt a configuration in which the particle diameters are divided in many stages, aligned and conveyed.

<Second Embodiment>
Next, a second embodiment according to the present invention will be described.
Similarly to the first embodiment, the second embodiment shows another example of the sizing / aligning unit 5 used in the sorting system for industrial waste or the like shown in FIG.

  The second embodiment is the industrial waste described in the first embodiment except that the sorting feeder 5 is replaced with the sorting feeder 200 instead of the sorting feeder 100 in the first embodiment. Therefore, the detailed description of the entire system is omitted, and only the alignment feeder 200 according to the second embodiment is described.

  As shown in FIG. 5, the alignment feeder 200 (partition plate system) according to the present embodiment has a discard that is an example of an object to be aligned and conveyed from the input unit 210, as in the first embodiment. Things are thrown continuously.

  Various wastes dropped from the loading unit 210 are guided to the conveyance unit 220 functioning as a vibration feeder. First, the waste dropped from the loading unit 210 is transferred to the partition plate 221 in FIG. It is guided to the left conveyance path 222A.

Note that both sides of the transport unit 220 in the transport direction are defined by a left side wall 240 and a right side wall 250 extending in the transport direction with a predetermined height.
Further, the whole shown in FIG. 5 is vibrated through an electric motor or the like with a predetermined amplitude at a predetermined cycle.

  Here, since the conveyance part 220 functions as a vibration feeder, the conveyance force resulting from the energy by the free fall which remains and the conveyance force provided by a vibration act on the thrown-in waste.

  Moreover, the conveyance part 220 has the inclined surface 222 to which the right direction of FIG. 5 fell similarly to the conveyance part 120 of 1st Embodiment.

  For this reason, as shown in FIGS. 5 and 6, the force (GF) of the gravity component (falling direction component) traveling in the right direction in FIG. 5 acts on the waste on the inclined surface 222 of the transport unit 220. Therefore, on the inclined surface 222, the waste is transported obliquely with respect to the transport direction by the transport force (CF) due to vibration and the force (GF) of the gravitational component (fall direction component). (RF) acts.

  In addition, as shown in FIG. 6 etc., the inclined surface 222 is inclined in the traveling direction so that the downstream side in the transport direction is slightly lower than the upstream side (forward tilt) (when the transport force of the vibration feeder in the transport direction is strong) Etc. can also be arranged at the opposite inclination (backward inclination)), and by adjusting the angle of the traveling direction inclination (forward inclination, backward inclination), for example, a desired Fine adjustment is possible to obtain the conveyance speed.

  In the present embodiment, wastes of a predetermined size or larger in the conveyance path 222A on the left side of the partition plate 221 in FIG. 5 are moved along the inclined surface 222 by the force in the direction of gravity (drop direction component) on the right side in FIG. A partition plate 221 that forms an opening (gap) of a predetermined height from the surface of the inclined surface 222 is formed on the frame member 223 as shown in FIGS. 5, 6, and the like so as to restrict the rolling down to the conveyance path 222 </ b> B side. It is attached.

  Therefore, the size of the waste transported in the transport path 222A on the left side of the partition plate 221 in FIG. 5 is larger than the opening (gap) between the lower end of the partition plate 221 and the upper surface of the inclined surface 222 (larger). Since the waste (having a diameter) cannot pass through the opening (gap), it does not fall to the transport path 222B on the right side in FIG. Led to.

  On the other hand, of the waste conveyed in the conveyance path 222 </ b> A on the left side of the partition plate 221 in FIG. 5, the size is larger than the opening (gap) between the lower end of the partition plate 221 and the upper surface of the inclined surface 222. Small (small-diameter) waste passes through the opening (gap), is dropped to the conveyance path 222B on the right side in FIG. 5, and is guided to the small-diameter lane 230B of the discharge unit 230.

  Therefore, according to the alignment feeder 200 according to the present embodiment, the relatively large size (large diameter) waste and the relatively small size (small diameter) waste are reliably sized (sorted). be able to.

  Here, when the present inventors are conducting an experiment, the opening (gap) formed between the lower end of the partition plate 221 and the upper surface of the inclined surface 222 is a gap having the same size in the transport direction. In some cases, waste was clogged.

  In order to suppress this clogging phenomenon, the present inventors have made various experimental studies and obtained the following knowledge.

  That is, the partition plate 221 is attached with an angle in advance so that the gap formed between the lower end of the partition plate 221 and the upper surface of the inclined surface 222 increases toward the downstream side in the transport direction. Thus, it was confirmed that clogging of waste can be effectively suppressed.

  In this experiment, since the waste was divided at a grain size of about 100 mm, the height from the inclined plate 222 to the partition plate 221 was about 60 mm (upstream in the transport direction) to 100 mm (downstream in the transport direction). Until changed. That is, the partition plate 221 was attached so that the inclination angle with respect to the inclined surface 222 was about 5 °.

  As a result, the gap widens in the vibration feeding direction (traveling direction), so that clogging of waste can be eliminated, and subsequent waste flows even if a phenomenon occurs in which waste clogs the gap. It was confirmed that the clogging waste was pushed and the clogging was removed.

  As described above, when the partition plate 221 is attached so that the gap formed between the lower end of the partition plate 221 and the upper surface of the inclined surface 222 becomes larger toward the downstream side in the transport direction, the partition plate 221 is transported. When it is long along the direction, the gap becomes excessive on the downstream side, and the excessive portion cannot function as the partition plate 221 (that is, the sizing function).

  For this reason, in this embodiment, as shown in detail in FIG. 6, the partition plate 221 is divided into a plurality of parts in the transport direction.

  That is, here, for example, the partition plate 221 is divided into two along the transport direction, and the upstream partition plate 221A and the downstream partition plate 221B are provided.

  The gaps between the partition plates 221A and 221B can be set as appropriate according to the size of the waste to be sized. 221b (about 60 mm upstream and about 100 mm downstream).

  Thereby, for example, the waste can be accurately and reliably sized with a particle diameter of about 100 mm as a boundary.

  However, if the upstream side partition plate 221A and the downstream side partition plate 221B are simply provided in series, there is a possibility that the connection portion is clogged with waste as shown in FIG.

For this reason, in this embodiment, a gap (offset) Y is provided between the downstream end of the partition plate 221A and the upstream end of the partition plate 221B in the width direction of the waste conveyance direction. , To prevent clogging of waste.
That is, the shallower the gap angle between the partition plate and the inclined surface, the higher the possibility that the waste will be clogged. Therefore, the clogging is eliminated by arranging a plurality of partition plates having a steep gap angle. However, if the gap once widened by the upstream partition plate is suddenly narrowed by the downstream partition plate, it will naturally cause clogging. Therefore, clogging is eliminated by providing a gap also in the Y direction.

  In the present embodiment, as shown in FIG. 5 and the like, the partition plates are arranged in a row in the width direction in the transport direction, and the transport paths 222A and 222B are provided so as to be divided into a large diameter and a small diameter. However, by providing the partition plates in multiple stages in the width direction of the conveyance direction and adjusting the gaps appropriately so as to provide conveyance paths corresponding to the respective stages, not only in large diameters and small diameters, but in more stages. It is also possible to divide the particle size, arrange and discharge.

  In each of the large-diameter lane 230A and the small-diameter lane 230B, the wastes are conveyed side by side along the conveyance direction.

  According to the present embodiment, since the particles are sized according to the size, it is possible to prevent entry into the lower side of the adjacent waste in each lane. Can be transported in an aligned state.

  That is, according to the present embodiment, it is possible to classify wastes having different shapes and sizes, and transport the sorted wastes in alignment with the transport path corresponding to the particle diameter.

  Further, in the present embodiment, since waste is blocked in the middle of the conveyance path and a phenomenon such as clogging is suppressed, a relatively large and time-consuming removal operation is required. There are few cases, and even if waste is continuously charged, for example, it is less necessary for humans to constantly monitor the occurrence of clogging, so automatic operation is possible, for example, compared to conventional devices, Work efficiency can be greatly improved.

  In this embodiment, a phenomenon is also assumed in which adjacent wastes in the lanes of the large diameter lane 230A and the small diameter lane 230B come in close contact with each other in the transport direction, but also in this embodiment, Since the belt conveyor 6A is connected to the downstream side of the large-diameter lane 230A and the small-diameter lane 230B, a relatively small size waste and a relatively large size waste from each lane are thereby transferred onto the belt conveyor 6A. Although supplied (by dropping or the like), a relatively small size waste and a relatively large size waste can be distinguished in the width direction of the belt conveyor 6A.

  Further, by setting the conveyance speed of the belt conveyor 6A to be higher than the conveyance speed by the vibration of the alignment feeder 200 (large diameter lane 230A, small diameter lane 230B), even if the waste is close to the conveyance speed Since the interval between the adjacent wastes can be widened by the speed difference, the interval between the wastes in the transport direction of the belt conveyor 6A can be made predetermined.

  Accordingly, the material determination unit 6 can individually determine the materials of the wastes supplied from the small-diameter lane 130A and determine the material of each waste with high accuracy, and similarly, the waste supplied from the large-diameter lane 130B. The material of each waste can be determined with high accuracy by individualizing the material.

  In the present embodiment, regarding the belt conveyor 6A, the waste carried out from the large-diameter lane 230A and the waste carried out from the small-diameter lane 230B are configured to be placed on a common belt. It can be set as the structure provided with an independent belt conveyor corresponding to a lane. Thereby, since the conveyance speed of a belt conveyor can be set independently corresponding to each lane, it is useful when, for example, it is desired to further improve the material determination accuracy of the material determination unit 6.

In addition, according to the 1st, 2nd embodiment which concerns on this invention, there can exist the following specific effects.
(1) While conveying solids (waste materials) of different shapes and sizes, they can be separated into large sizes (large diameter) and small sizes (small diameter) and discharged (no sieve is required).
(2) The size of the waste can be sorted at an arbitrary stage by forming the bank body part and the partition plate in a plurality of stages in the width direction of the conveyance direction.
(3) By dividing into large diameters and small diameters as described above, it is possible to suppress the overlapping and overcoming of the wastes during the transport process, and therefore, it is possible to align the wastes in the transport direction.
(4) In the sorting system as shown in FIG. 1, since the function as a sieve, the function of conveying, and the function of aligning can be performed by one of the aligning feeders 100 (200), the number of devices constituting the system Therefore, it is possible to promote downsizing of the entire system and to reduce the cost.
(5) Since the alignment feeder 100 (200) performs conveyance, sizing, and alignment using the height difference from upstream to downstream, it is not necessary to separately provide a conveyance device or alignment device below the vibration screen. The number of devices constituting the system can be reduced and the height of the entire system can be reduced.
(6) Since the number of devices constituting the system can be reduced, power sources such as motors and movable parts can be reduced, so that the noise of the entire system can be reduced.

  By the way, in the first embodiment, it is also possible to adopt a layout in which the alignment feeder 100 is arranged facing the surface object with the left side wall 140 as the center. In that case, for example, the left side wall 140 may be omitted.

  Similarly, in the second embodiment, it is also possible to adopt a layout in which the alignment feeder 200 is disposed facing the surface object with the left side wall 240 as the center. In that case, for example, the left side wall 240 may be omitted.

  In each of the embodiments, the waste has been described as an object of sizing and alignment conveyance. However, the present invention is not limited to this, and can be a solid object other than waste.

  The embodiments according to the present invention described above are merely examples for explaining the present invention, and various modifications can be made without departing from the gist of the present invention.
