[0001]
BACKGROUND OF THE INVENTION
The present invention, sorting apparatus of waste plastics to separate waste plastics consisting of hard plastic toys such as near a plastic bottle and shape which the waste in a plastic is recyclable garbage into the material by and Color, etc., as well as plastic bottles concerning alignment apparatus of waste plastics arranging in a plurality of rows of.
[0002]
[Prior art]
It is known that the near-infrared absorption spectrum of plastic is unique depending on the material. In Europe, which is an environmentally advanced country, an automatic sorting device for waste plastic bottles using a measuring means for identifying a material by such a near-infrared light absorption spectrum has been developed and commercialized (see Japanese Patent Laid-Open 9-220532). Also in Japan, technical development related to such technology has been active for several years, and several technologies have been published (Japanese Patent Laid-Open Nos. 8-1101 and 9-89768, (Kaihei 9-220532).
[0003]
Such a measurement speed of the plastic material by the near-infrared light absorption spectrum is 0.01 per point by a spectroscopic system based on a combination of a near-infrared spectroscopic element and a one-dimensional solid-state image sensor usable in the near-infrared region. Something less than a second has been developed. In addition, the measurement speed of plastic color is being performed in a very short time. Accordingly, the processing capacity of the automatic sorting system for waste plastic bottles and the like is determined by the speed at which the waste plastic bottles and the like that are miscellaneously input are aligned.
[0004]
However, waste plastic bottles and the like are often compressed and flattened and are light, and it is extremely difficult to align the waste plastic bottles and the like.
[0005]
The present applicant has proposed a waste plastic sorting device in which waste plastic bottles and the like are quickly aligned in a line, these materials are detected by a sensor, and these are sorted by material (Japanese Patent Application No. 11-353519). issue).
[0006]
[Problems to be solved by the invention]
However, in this waste plastic sorting apparatus, the waste plastic bottles can be quickly aligned in a line, but as long as the waste plastic bottles are aligned in a line, the processing capability of the sorting apparatus cannot be dramatically improved. In other words, in order to increase the throughput with a single sorting device, it is indispensable to arrange waste plastic bottles in parallel.
[0007]
In order to solve this problem and arrange waste plastics in multiple rows, the present applicant has provided a posture control conveyor for controlling the posture of the thrown plastics disposed above the transport conveyor, and the linear member constituting the posture control conveyor. The waste plastics thrown onto the linear members are dropped onto the transport conveyor from both sides of the linear members, and the waste plastics are arranged in the longitudinal direction on the transport conveyor. A waste plastic multi-row aligning apparatus for paralleling the multi-rows is proposed (Japanese Patent Application No. 12-010081).
[0008]
The present invention relates to an improvement of the above-described technique, and an object of the present invention is to provide a multi-row aligning apparatus for waste plastics and a multi-row aligning apparatus capable of arranging a multi-row array of waste plastic bottles arranged in the longitudinal direction. It is to a sorting device for waste plastics using a multiple column alignment device more that more excellent.
[0009]
[Means for Solving the Problems]
The present invention will be described below. In addition, in order to make an understanding of this invention easy, the reference number of an accompanying drawing is attached in parenthesis writing, However, This invention is not limited to the form of illustration.
[0010]
In the waste plastic sorting apparatus described in Japanese Patent Application No. 12-010081, bars extending in the transport direction at predetermined intervals are arranged on the transport surface of the transport conveyor. This bar is for allowing waste plastics falling in parallel from above to flow in the same conveying line without interfering with each other during the conveying. However, this crosspiece increases the manufacturing cost of the transfer conveyor and lowers the durability of the belt in a resin-type belt conveyor. The present inventor has found that by providing two upper and lower linear members above the transport conveyor and operating the lower linear member in the transport direction, a crosspiece can be omitted on the transport surface of the transport conveyor. .
[0011]
The invention of claim 1 includes a conveyor for conveying the plastic bottles and this consists of a hard plastic such shape is close toys waste plastics in waste plastic (3), disposed above the conveyor (3) A posture control conveyor (7) for controlling the posture of the waste plastics and dropping it onto the transport conveyor (3), the posture control conveyor (7) extending in the transport direction of the transport conveyor (3) It has at least two linear members (9a, 9b) and a fixing member (11) , and the at least two linear members (9a, 9b) are arranged one above the other, and the upper linear member (9a) the conveying direction opposite to the direction of the conveyor (3), below the linear member (9b) is operated in the same direction as the conveying direction of the conveyor (3), said fixing member (11) Characterized in that it is arranged substantially in parallel at predetermined intervals on opposite sides of the linear member (9a, 9b).
[0012]
Upper linear member, after a randomly put the discarded plastics rotated to be parallel with the linear member, dropping the waste plastics on conveyor from both sides of the linear member. Accordingly, falls on the transport conveyor in a state waste plastics are arranged in multiple rows. Further, to flow the same conveying line waste plastics that linear member beneath have been dropped from above in parallel without interfering with each other. Therefore, a crosspiece can be omitted on the transfer surface of the transfer conveyor.
[0013]
Here, as the linear member, a linear member having a longer length in the vertical direction than the lateral width of a wire, a chain, a belt, or the like can be used. Various conveyors such as a belt conveyor, a mesh conveyor, a chain conveyor, a roller conveyor, and a vibration conveyor can be used as the conveyor.
[0014]
Random waste plastics that have been introduced on the attitude control conveyor raises rests across the linear member fixing member and the upper. Since the linear member is operated, waste plastics rotates the fixing member as a fulcrum, become parallel to the gap between the linear member and the fixed member, falls onto the conveyor from the gap.
[0015]
According to a second aspect of the present invention , in the multi-row alignment apparatus for waste plastics according to the first aspect, the speed of the lower linear member (9b) is higher than the speed of the conveyor (3). It is characterized by being.
[0016]
By making the speed of the lower linear member higher than the speed of the conveyor , the posture of the waste plastics can be further corrected. That is , when the posture of the discarded plastics is not parallel to the transport direction and a part thereof touches the linear member, the touched part is pulled forward, and the posture of the waste plastics becomes more parallel to the transport direction.
[0017]
Further, the invention of claim 3, configured in multiple rows alignment apparatus of waste plastics according to claim 1 or 2, wherein the posture control conveyor (7), the two linear members (9a, 9b) and And a driving vehicle (8a) and a driven vehicle (8b) disposed at both ends of the winding mediating node (9).
[0018]
According to the present invention, since the winding intermediate node constitutes two linear members, the structure of the attitude control conveyor can be simplified.
[0019]
Further, characterized in that the invention of claim 4, in multiple rows alignment apparatus of waste plastics according to claim 1 to 3, the linear member (9a, 9b) is the cross section has a hexagonal And
[0020]
When a V-belt is used for the linear member, there is a problem that a plastic bottle can easily be put on the back surface of the V-belt and it is difficult to fall. By using the hexagonal belt having a hexagonal cross section to a linear member, it is possible to prevent the splashing of waste plastics, to improve the durability of the belt. Of course, a circular cross section may be used, but a hexagonal belt is optimal from a practical viewpoint such as durability and availability.
[0021]
Incidentally, when aligned plastic bottles only one row, so as to sandwich the waste plastics from both sides in the lateral direction (horizontal direction), it is possible to arrange the detecting means utilizing the transmitted light. However, when waste plastics are arranged in a large number of rows, it is not possible to arrange detection means using transmitted light so as to sandwich the plastic bottle from both sides in the horizontal direction (horizontal direction). For this reason, in the waste plastic sorting apparatus described in the above-mentioned Japanese Patent Application No. 12-010081, a mesh conveyor capable of transmitting light through the transport surface is used as the transport conveyor, and the waste plastic is disposed in the vertical direction (vertical direction). The detecting means is arranged so as to be sandwiched from both sides.
[0022]
When detecting the properties of plastic bottles such as color and material using only reflected light, it is only necessary to provide detection means that uses reflected light only on one side of the conveyor, and use a resin belt instead of a mesh on the conveyor. Can do. However, for example, when detecting the color of a plastic bottle, detection means using transmitted light is convenient. In detecting means utilizing reflected light, because also detects the color of the label on the waste plastics, but the light is blocked by the label in utilizing transmitted light detecting means, the label is black, waste plastics This is because only the color can be easily extracted. Also, placing a reflector of light to the back side of the waste plastics case of detecting the material of plastic or the like in the absorption spectrum of near infrared light, and the change and disposal plastics of the reflected light at the projection side of light reciprocally transmitted Write the absorption spectrum was measured by the waste plastics from the change in the optical measurement accuracy can be improved. This is remarkable when waste plastics of the object to be measured is a transparent or light color. Therefore, to detect the waste plastics by utilizing transmitted light detection means is desirable.
[0023]
However, in the detecting means utilizing transmitted light was installed reflector illumination or light below the conveying surface of the mesh conveyor, the dust adhering to the liquid or waste plastics drinking leaving such as plastic bottles, lower It often happens that the lighting or the light reflector is soiled.
[0024]
In order to solve this problem, the present inventor devised the positional relationship between the upper side and the lower side of the detection means, provided the detection means so that the waste plastics are sandwiched from above and below the transfer conveyor, and the detection means the lower side is arranged below the conveyor, and the arrangement can detect the direction from the waste plastics inclined obliquely with respect to the vertical line.
[0025]
That is, the invention of claim 5 includes a conveyor for conveying side by side waste plastics plastic bottles and shape to the waste in the plastic consists of hard plastic near toys in a plurality of rows (3), waste plastics and detection detecting means (4a, 4b), based on said detection means (4a, 4b) is detected by the information, and a sorting means for sorting the waste plastics (5), said detection means (4a, 4b) is together provided transit portion of the transit portion or said conveyor (3) and glide chute (16) or the like of a plurality of said conveyor (3), the waste plastics and so as to sandwich from above and below the lower side (4b) and An upper side (4a), and a lower side (4b) of the detection means is arranged under the conveyor (3), the detection In the upper side (4a) and sorting device for waste plastics which is a line connecting the lower side (4b) are inclined with respect to the vertical line of the stage, provided above the conveyor (3), waste plastics A posture control conveyor (7) for controlling the posture of the conveyor and dropping it onto the transport conveyor (3), the posture control conveyor including at least two linear members (9a, 9b) extending in the transport direction of the transport conveyor. ) And a fixing member (11) , the at least two linear members (9a, 9b) are arranged vertically, and the upper linear member (9a) is in a direction opposite to the conveying direction of the conveying conveyor. The lower linear member (9b) is operated in the same direction as the conveying direction of the conveyor (3), and the fixed member (11) is spaced at a predetermined interval on both sides of the linear members (9a, 9b). Open and parallel Is the fact characterized.
[0026]
According to the present invention, the detection means color of waste plastics, to detect the material and the like. Then, based on the detected information, the sorting means sorts waste plastics. Since the waste plastics are arranged in a large number of rows, the sorting device can sort the multiple rows at the same time, and the processing capacity is dramatically improved. Also, with the lower side of the detecting means disposed below the conveyor, by an arrangement for detecting the waste plastics which protrudes in transit from an oblique direction, the residual liquid of waste plastics below the detection means It is possible to prevent dust from adhering to it.
[0027]
