Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for separating waste plastics for separating plastic bottles in waste plastics, which are resource refuse, and hard plastics such as toys having a shape close to the plastic bottles, according to material and color, and the like. The present invention relates to a waste plastic sorting device for arranging bottles and the like in a plurality of rows.

[0002]

2. Description of the Related Art It is known that the near-infrared absorption spectrum of plastic is more specific to its material. In Europe, an environmentally advanced country, an automatic sorting apparatus for waste plastic bottles using a measuring means for specifying a material using such near-infrared light absorption spectrum has been developed from early on and has been commercialized (Japanese Patent Laid-Open No. 9-220532
No.). Also, in Japan, technology development related to such technology has been active in recent years, and some technologies have been disclosed (Japanese Patent Application Laid-Open Nos. 8-1101 and 9-89768, JP-A-9-220532).

[0003] The measuring speed of a plastic material based on the near-infrared light absorption spectrum can be determined by a spectroscopic system using a combination of a near-infrared spectroscopic element and a one-dimensional solid-state imaging device usable in the near-infrared region. Those with less than 0.01 seconds have also been developed. Also, the speed of measuring the color of plastics has been increasing in a very short time. Therefore, the processing capacity of the automatic sorting system for waste plastic bottles and the like is determined by the speed at which miscellaneously placed waste plastic bottles and the like are aligned.

However, waste plastic bottles and the like
Since it is often compressed and crushed flat and light, it is extremely difficult to align waste plastic bottles and the like.

The applicant of the present invention has proposed a waste plastic sorting apparatus that quickly arranges waste plastic bottles and the like in a line, detects these materials and the like with a sensor, and sorts them according to the material (Japanese Patent Application No. Hei. 11-353519).

[0006]

However, in this waste plastic sorting apparatus, waste plastic bottles can be quickly arranged in a line, but as long as the waste plastic bottles are arranged in a single line, the processing capacity of the sorting apparatus is dramatically increased. Can't improve. In other words, it is indispensable to arrange a large number of waste plastic bottles in parallel in order to increase the throughput with one sorting apparatus.

In order to solve this problem and arrange the waste plastics in a large number of rows, the present applicant provides an attitude control conveyor for controlling the attitude of the input waste plastic above the transport conveyor to constitute an attitude control conveyor. The linear member is operated in the axial direction thereof, and the waste plastic put on the linear member is dropped on both sides of the linear member onto the transport conveyor, and the waste plastic is placed on the transport conveyor in the longitudinal direction. There has been proposed a multi-row aligning apparatus for waste plastics in which the aligned rows are arranged in parallel in multiple rows (Japanese Patent Application No. 12-01081).

The present invention relates to an improvement of the above-mentioned technology, and an object of the present invention is to provide a waste plastic multi-row aligning apparatus capable of juxtaposing a plurality of rows of waste plastic bottles or the like arranged in the longitudinal direction thereof. Another object of the present invention is to further improve a waste plastic sorting apparatus using the multi-row aligning apparatus.

[0009]

Hereinafter, the present invention will be described. In addition, in order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are added in parentheses, but the present invention is not limited to the illustrated embodiment.

[0010] In the waste plastic sorting apparatus described in Japanese Patent Application No. 12-01081, a beam extending in the transport direction is arranged at a predetermined interval on the transport surface of the transport conveyor. This crossbar is for allowing the waste plastics dropped in parallel from above to flow on the same transport line without interfering with each other during the transport. However, this bar increases the production cost of the conveyor,
A resin-based belt conveyor reduces the durability of the belt. The present inventor has found that by providing two upper and lower linear members above the transport conveyor and operating the lower linear members in the transport direction, the bars can be omitted on the transport surface of the transport conveyor. .

That is, according to the first aspect of the present invention, there is provided a conveyor (3) for transporting waste plastic, and the transport conveyor (3) provided above the transport conveyor (3) and controlling the attitude of the waste plastic. And a posture control conveyor (7) for dropping upward, the posture control conveyor (7) having at least two linear members (9a, 9b) extending in the conveyance direction of the conveyance conveyor (3), The at least two linear members (9a, 9b) are arranged one above the other, and the upper linear member (9a) is connected to the conveyor (3).
And the lower linear member (9b) is operated in the same direction as the transport direction of the transport conveyor (3).

The upper linear member rotates the waste plastic that has been randomly charged until it is parallel to the linear member, and then drops the waste plastic from both sides of the linear member onto the conveyor. As a result, the waste plastics fall on the transport conveyor in a state of being arranged in many rows. In addition, the lower linear members are made to flow through the same transport line without interfering with the waste plastics dropped in parallel from the upper side. Therefore, the crosspiece can be omitted on the transport surface of the transport conveyor.

Here, as the linear member, a linear member such as a wire, a chain, a belt, or the like, whose longitudinal length is longer than the horizontal width can be used. Also, on the conveyor,
Various conveyors such as a belt conveyor, a mesh conveyor, a chain conveyor, a roller conveyor, and a vibration conveyor can be used.

According to a second aspect of the present invention, in the multi-row aligning apparatus according to the first aspect, the lower linear member (9
The speed of b) is higher than the speed of the conveyor (3).

By making the speed of the lower linear member higher than the speed of the conveyor, the posture of the waste plastic can be further corrected. That is, when the position of the dropped waste plastic is not parallel to the transport direction and a part of the waste plastic touches the linear member, the touched part is pulled out forward, and the posture of the waste plastic becomes more parallel to the transport direction.

[0016] The invention of claim 3 is the invention of claim 1 or 2.
In the multi-row aligner for waste plastic according to the above,
The attitude control conveyor (7) includes a winding intermediate node (9) that forms the two linear members (9a, 9b), and motor vehicles (20) disposed at both ends of the winding intermediate node (9). 8a)
And a driven vehicle (8b).

According to the present invention, since the winding intermediate node forms two linear members, the structure of the attitude control conveyor can be simplified.

According to a fourth aspect of the present invention, in the multi-row waste plastic aligning apparatus according to any one of the first to third aspects, the linear member (9) has a hexagonal cross section. And

If a V-belt is used as the linear member, a problem arises in that the plastic bottle is easy to ride on the back surface of the V-belt and it is difficult to drop. By using a hexagonal belt having a hexagonal cross section as the linear belt, it is possible to prevent waste plastic from splashing and to improve the durability of the belt. Of course, the cross section may be circular, but a hexagonal belt is optimal from a practical viewpoint such as durability and availability.

Further, according to a fifth aspect of the present invention, in the multi-row aligning apparatus for waste plastic according to any one of the first to fourth aspects, the attitude control conveyor (7) is provided with the linear member (9a, 9b). It is characterized in that it has fixing members (11) arranged on both sides in a substantially parallel manner with a predetermined space therebetween.

According to the present invention, the waste plastics randomly placed on the attitude control conveyor are loaded over the fixed member and the upper linear member. As the linear member operates, the waste plastic rotates around the fixing member as a fulcrum, and becomes parallel to the gap between the linear member and the fixing member.
It falls on the conveyor from this gap.

By the way, when the plastic bottles are arranged in only one line, the detecting means using the transmitted light can be arranged so as to sandwich the waste plastic from both sides in the horizontal direction. However, when a large number of waste plastics are arranged in rows, it is not possible to arrange the detecting means using transmitted light so as to sandwich the plastic bottle from both sides in the horizontal direction. For this reason, in the waste plastic sorting apparatus described in Japanese Patent Application No. Hei 12-010081, a mesh conveyor capable of transmitting light through a transport surface is used as a transport conveyor, and the waste plastic is vertically moved (vertically). The detection means is arranged so as to sandwich it from both sides.

When the properties of the plastic bottle such as color and material are detected only by the reflected light, a detecting means utilizing the reflected light may be provided only on one side of the conveyor, and the conveyor may be provided with a resin belt or the like instead of a mesh. Can be used. However, for example, in the case of detecting the color of a plastic bottle, a detecting means using transmitted light is convenient. Because the detection means using reflected light also detects the color of the label affixed to the waste plastic, the detection means using transmitted light blocks the light with the label and the label becomes black,
This is because only the color of the waste plastic can be easily extracted. Also, when detecting a material such as plastic in the absorption spectrum of near-infrared light, a light reflector is placed on the back side of the waste plastic, and the change in the reflected light on the light projection side and the light reciprocated through the waste plastic are reflected. The measurement accuracy is improved by measuring the absorption spectrum of the waste plastic from the change. This is remarkable when the waste plastic of the object to be measured is transparent or light-colored. Therefore, it is desirable to detect the waste plastic by the detecting means using the transmitted light.

However, in the detection means utilizing transmitted light provided with a lighting or light reflecting plate below the conveying surface of the mesh conveyor, the liquid remaining in the drinking water such as a plastic bottle or the dust adhering to the waste plastic is used. Frequently, the lower lighting or light reflector becomes dirty.

In order to solve this problem, the present inventor has devised the positional relationship between the upper side and the lower side of the detecting means, and provided the detecting means so as to sandwich the waste plastic from above and below at the connecting portion of the transport conveyor. The lower side of the means is arranged below the conveyor, and the arrangement is such that the waste plastic can be detected from a direction obliquely inclined with respect to the vertical line. That is, according to the invention of claim 6, a conveyor (3) for conveying waste plastics in a plurality of rows, detection means (4a, 4b) for detecting waste plastics, and detection by the detection means (4a, 4b). And a sorting unit (5) for sorting waste plastics based on the obtained information.
a, 4b) are provided at a connecting portion between the plurality of transporting conveyors (3) or at a connecting portion between the transporting conveyor (3) and the glide chute (16) and the like, and are disposed below so as to sandwich the waste plastic from above and below. Side (4b) and an upper side (4a), and the lower side (4
b) is disposed below the conveyor (3), and a line connecting the upper side (4a) and the lower side (4b) of the detection means is inclined with respect to the vertical line.

According to the present invention, the detecting means detects the color, material and the like of the waste plastic. Then, the sorting means sorts the waste plastic based on the detected information.
Since the waste plastics are arranged in multiple rows, the sorting apparatus can sort multiple rows at the same time, and the processing capacity is dramatically improved. In addition, by disposing the lower side of the detecting means below the conveyor and detecting the waste plastic that is jumping out during the transfer from an oblique direction, the residual liquid and adhesion of the waste plastic can be seen below the detecting means. You can make sure that the dust you do not catch.

The detecting means includes a color CCD camera (upper side) for identifying the color of the waste plastic and illumination (lower side), or a near-infrared light sensor (upper side) for identifying the material and a reflecting plate (upper side). It is possible to use a CCD camera (upper side) and a lighting (lower side) with a deflection filter for identifying colors and materials, or the like. As the sorting means, an air nozzle, an air opening / closing valve, and the like provided on the downstream side of the transport conveyor can be used.

According to a seventh aspect of the present invention, there is provided the waste plastic sorting apparatus according to the sixth aspect, wherein a lower side (4b) of the detection means and the transport conveyor (3) are provided.
A dirt prevention unit (1) is provided so that the lower side of the detection means is not stained.
7) is provided.

According to the present invention, the dirt preventing portion prevents the residual liquid of the waste plastic and the attached dust from being applied to the lower side of the detecting means.

Further, according to the invention of claim 8, in the waste plastic sorting apparatus according to claim 6 or 7, the waste plastic sorting apparatus is provided above the transport conveyor (3) and controls the posture of the waste plastic to control the transport plastic. (3) An attitude control conveyor (7) for dropping on the top, the attitude control conveyor (7) having at least two linear members (9a, 9b) extending in the transport direction of the transport conveyor (3). And
The at least two linear members (9a, 9b) are vertically arranged, and the upper linear member (9a) is a lower linear member (9b) in a direction opposite to the transport direction of the transport conveyor (3).
Is operated in the same direction as the transport direction of the transport conveyor (3). According to the present invention, the crosspiece can be omitted on the transport surface of the transport conveyor for the above-described reason.

The attitude control conveyors 7, 7 are transport conveyors 3.
Are provided in parallel with the transport direction so that four rows of waste plastic are arranged on the transport surface. Each of the attitude control conveyors 7 controls the attitude of the waste plastic so that the waste plastic is arranged in a line in the longitudinal direction. Each of the attitude control conveyors 7, 7 is configured by bridging a winding intermediate node between the driving vehicle 8a and the driven vehicle 8b. The center axes of the driving vehicle 8a and the driven vehicle 8b are installed parallel to the transport surface of the transport conveyor 3 and perpendicular to the transport direction.

The two linear members 9a and 9b constituting the winding intermediate node 9 are arranged vertically in a plane formed by the transport direction and the vertical direction. A linear member 9b, here the return side of the looping intermediate node 9, is arranged immediately above the transport surface. The upper linear member 9a is operated in the direction opposite to the conveying direction of the conveyor 3, and the lower linear member 9b is operated in the same direction as the conveying direction of the conveyor 3. The speed of the lower linear member 9 b is set to be higher than the speed of the conveyor 3. The linear member 9 has a hexagonal cross section as shown in FIG. Note that the linear member 9 is not limited to a belt having a hexagonal cross section, but may be a chain, a belt, or the like.

3b. A central guide 13b is arranged between the pair of left and right linear members 9 and 9, and side guides 13a and 13a are arranged beside the pair of left and right linear members 9 and 9. In this embodiment, a total of four rows of waste plastic transport paths are formed between the linear members 9 and 9 and the fixed guide 11. The width of the transport path is set, for example, to a total length of 250 to 350 mm or less in the longitudinal direction of the plastic bottle 6 to be put (see FIG. 6).

FIG. 5 shows a cross section of the multi-row aligner 1 at the position of the separating conveyor 2. The separation conveyor 2 is a kind of a general continuous transport machine for horizontally transporting waste plastic, like the transport conveyor 3. As the separation conveyor 2, for example, a belt conveyor, a mesh conveyor, a chain conveyor, a roller conveyor, a vibration conveyor, or the like is used. The waste plastics arranged in a plurality of rows on the conveyor 3 are separated by the separation conveyor 2 one by one in each row. A bar 14 is formed on the transport surface of the separation conveyor 2 to prevent waste plastic from overlapping on the transport surface.

FIG. 6 shows a sorting device downstream of the separation conveyor 2. A plurality of detecting devices 4a and 4b for detecting waste plastic are provided at a connecting portion between the conveyor 3 and the gliding chute 16 in accordance with the number of rows of waste plastic. The detecting devices 4a and 4b have an upper side 4a and a lower side 4b so as to sandwich the waste plastic that comes out of the separation conveyor 3 from above and below. When detecting the color of the waste plastic, the lower side 4b of the detector is used.
In the upper side 4a, a photographing element such as a color CCD camera can be used. When detecting the material of waste plastic, the lower side 4b has a reflecting plate, and the upper side 4a has near-infrared light. Sensors can be used.

The line connecting the upper side 4a and the lower side 4b of the detection device is inclined with respect to the vertical line so as to detect waste plastic from an oblique direction. As a result, the optical axis of the sensor or the like is pulled apart and obliquely passes through the gap between the terminal end of the conveyor 3 and the gliding chute 16. Further, the lower side 4b of the detection device is arranged below the conveyor 3. Further, a dirt prevention cover 17 is provided between the lower side 4b of the detection device and the conveyor 3 so as to prevent the lower side 4b of the detection device from being soiled. The lower side 4b of the detection device is arranged so as to be hidden by the dirt prevention cover 17.

As a specific color detecting device, for example, JP-A-5-1276761, Japanese Patent Application No. 6-249
No. 312 can be used.
As a material detecting device, for example, Japanese Patent Application Laid-Open No. 6-308022
Can be used. As a color and material detecting device, for example, JP-A-2000-288
No. 481 can be used.

A passage sensor (not shown) for detecting passage of the waste plastic is provided upstream of the detection devices 4a and 4b. The passage sensor detects the tip, length, and the like of the waste plastic. Based on the detection value of this passage sensor,
The timing for operating the sorting device 5 described later is determined.

Sorting device 5 for sorting waste plastic
Are provided on the downstream side of the gliding chute 16 in accordance with the number of rows of waste plastic. The sorting device 5 is, for example,
It consists of an air nozzle and an air on-off valve. The on-off valve is opened and closed by the controller. Detection device 4a, 4b
Detects the color or material of the waste plastic, and the controller operates the on-off valve based on the detected information. When the on-off valve is opened, an air jet blows out from the air nozzle and blows away waste plastic. As a result, the waste plastic is sorted into normal substances and foreign substances, for example, into PET bottles and other PVC. The sorted waste plastics are put into sorting chutes 18a and 18b. Note that the sorting device 5 is not limited to an air nozzle and an air opening / closing valve, and may be a device that mechanically sorts using, for example, a lever.

In the waste plastic, steel cans and aluminum cans are mixed, and it may be necessary to sort them. In this case, a metal sensor for detecting metal may be added above the conveyor 3 and the sorting device 5 may be operated based on information detected by the metal sensor.

Next, the operation of the sorting apparatus according to the present embodiment will be described. An example in which a plastic bottle is put as waste plastic will be described. First, the plastic bottle 6 is put into the hopper. The plastic bottles 6 placed in the hopper have no direction, and these plastic bottles 6 straddle the upper linear member 9 a and the fixed guide 11. When the linear member 9a moves in the axial direction, the plastic bottle 6 is moved around the fixed guide 11 as a fulcrum.
a, rotates parallel to the linear member 9a and the fixed guide 11, and drops onto the conveyor 3 from the gap between the linear member 9a and the fixed guide 11. In addition, the lower linear members 9b are made to flow through the same transport line without interfering with the plastic bottles 6 dropped in parallel from above.

Since the speed of the lower linear member 9b is higher than the speed of the conveyor 3, the posture of the plastic bottle 6 can be further corrected at the position of the lower linear member 9b. That is, when the position of the dropped plastic bottle 6 is not parallel to the conveyance direction and a part thereof touches the linear member 9b, the touched portion is pulled out forward, and the posture of the plastic bottle 6 becomes more parallel to the conveyance direction. . In addition, the plastic bottles 6 transported in a plurality of rows on the conveyor 3 are separated by the separation conveyor 2 into individual rows. Since the separation conveyor 2 has the crosspiece 14 in the width direction, the plastic bottles 6 are conveyed in a state where they are aligned in each row.

The passing timing of the conveyed plastic bottles 6 is determined by passing sensors provided for each row, and the materials or colors are detected by the detecting devices 4a and 4b provided at the connecting portions. The information is processed by the controller, and the controller opens and closes the on-off valve of the sorting device 5. For example, when the plastic bottle 6 is a target PET bottle, the air jet is not operated, and the plastic bottle 6 is sorted by the inertia force of the plastic bottle 6a.
To get on top. On the other hand, when the plastic bottle 6 is other than a plastic bottle, the air jet is operated to put the plastic bottle 6 into the sorting chute 18b.

By arranging the lower side 4b (illumination or reflection plate) of the detecting device below the conveyor 3 and detecting the plastic bottle 6 that is popping out during the transit from an oblique direction, The liquid remaining in the plastic bottle 6 and the attached dust can be prevented from being applied to the lower side 4b. Further, the stain prevention cover 17 reliably prevents the lower side 4b of the detection device from being stained.

It should be noted that the present invention is not limited to the above embodiment, and various changes can be made. For example, three or more linear members 9 may be provided in a direction orthogonal to the transfer surface, and the detection devices 4a and 4b may be provided at a connecting portion of a plurality of transfer conveyors. Furthermore, the separation conveyor 2 can be omitted.

[0050]

As described above, according to the present invention,
The attitude control conveyor has at least two linear members extending in the transport direction of the transport conveyor, and the at least two linear members are arranged vertically, and the upper linear member is opposite to the transport direction of the transport conveyor. The lower linear member is driven in the same direction as the conveying direction of the conveyor. After rotating the waste plastic into which the upper linear member is randomly put in parallel with the linear member, the plastic is dropped on both sides of the linear member onto the conveyor. The lower linear member allows the waste plastics dropped in parallel from above to flow on the same transport line without interfering with each other. Therefore, the crosspiece can be omitted on the transport surface of the transport conveyor.

The detecting means is provided at a connecting portion of the plurality of transport conveyors or at a connecting portion of the transport conveyor and a gliding chute or the like, and has a lower side and an upper side so as to sandwich the waste plastic from above and below.
