Description

  The present invention relates to a trash box for promoting separation of trash.

  In recent years, with the deterioration of the global environment such as air pollution, the recycling of waste products has become more important, and each municipality and company has been thoroughly sorting waste. Under such circumstances, various trash bins have been proposed for efficiently collecting and separating trash.

  For example, in Patent Document 1, in a trash box in which an input attachment having a plurality of trash input ports formed thereon is attached, a plurality of trash bags are provided between the input attachment and the trash box so as to correspond to the trash input ports of the input attachment. There has been proposed a separation-type trash can that can dispose of various types of waste through the input attachment by providing a split attachment with the upper edge locked.

In addition, as a problem before sorting, a trash can has been proposed to improve manners for throwing trash into the trash. For example, Patent Documents 2 and 3 propose a recycle bin that is devised so that children can dispose of waste mainly in the recycle bin by decorating the recycle bin with popular characters, etc., and emitting sound and light when throwing in the recycle bin. ing.

  However, in recent years, trash boxes have often been removed from stations and facilities in order to reinforce warnings against terrorist acts triggered by the September 11th terrorist attacks on September 11, 2001. While this situation prevents terrorism, it also creates a problem of reduced manners such as leaving garbage and unsorted. Furthermore, regarding the unsorted waste, lack of knowledge, such as not knowing the material of the waste, is considered to be one of the factors due to the low awareness of waste sorting.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a trash box for promoting separation of trash.

  In order to solve the above-mentioned problems, a trash box according to the present invention includes an image pickup means for picking up a face image of a waste dumper, an image recording means for recording the face image, and a waste type for identifying a waste waste type. Identification means is provided, and the face image is recorded by the image recording means when the garbage type is not a collection target of the garbage can. Here, prior to recording the face image by the image recording means, warning means may be provided for warning the waste dumper.

  The trash box includes a lid that covers a trash input, a person detection unit that detects a person near the trash box in an imaging region of the imaging unit, and the lid is opened when a person is detected by the person detection unit You may have a lid drive means to do. Here, a weight detection sensor may be used as the person detection means.

  In addition, a waste storage chamber for holding the waste dumped from the waste inlet, two waste storage sections for separating and storing the waste, and a waste type of the waste held in the storage chamber You may provide the garbage classification identification means to identify, and the waste distribution means to distribute a waste into the said two waste storage parts based on the said garbage classification. Here, the waste sorting means is disposed so as to cover an opening provided on the upper surface of the two waste storage portions from above, and is mounted so as to be rotatable about a horizontal axis that bisects the main surface. You may comprise from the baseplate of a storage chamber, and the baseplate drive means which makes the bottomplate of the said storage storage chamber rotate in either direction, and inclines toward one of said two waste storage parts.

  Since the waste dumper can be monitored by the waste bin provided with such an image pickup means, manners of the waste dumper can be improved. In addition, since the trash dumper is warned when the trash is not the collection target, the trash dumper knows that the dumped trash is not the collection target, and can remove the trash before the face image is recorded. Furthermore, by detecting the approach of a person and automatically opening the lid, it is possible to improve convenience, and at the same time, avoiding bad behaviors such as throwing garbage from a distance by avoiding face images being recorded it can.

  In addition, by storing garbage in different places according to the type of garbage, even if a waste dumper with poor manners dumps garbage that is not subject to collection, the waste can be separated and collected. The work efficiency can be improved. Therefore, use of the trash box of the present invention has an effect of promoting trash separation.

  FIG. 1 shows a trash box according to the present invention. In the present embodiment, the garbage type that is collected by the garbage box 1 is, for example, plastic. The trash box 1 has an inclined surface at the top of a substantially rectangular parallelepiped main body 1, and a trash inlet 33 and a movable lid 3 covering the trash input 33 are provided on the inclined surface, and a speaker 6 is provided next to the trash box 1. Also, a lamp 5 is provided on the upper surface, and functions as a warning means that warns the waste dumper by sound output and lighting when dust other than the plastic to be collected is dumped together with the speaker 6.

  The movable lid 3 is automatically opened when the presence of a person is detected by the weight sensor 7 installed on the floor on the front side of the main body 2. The main body 2 and the weight sensor 7 are electrically connected by a sensor connection cable 11. This prevents an act of throwing garbage into the trash box 1 from a remote location in order to avoid taking a picture of the face with the camera unit 8 described later. The weight sensor 7 is covered with a mat 14 from the viewpoint of the aesthetic appearance of the trash can 1.

  A front door 4 is provided on the front surface of the main body 1 and can be opened by pulling the handle 15 after the key corresponding to the key hole 34 is put in and the lock is released. As will be described later, the main body 2 is provided with a storage box 28 (see FIGS. 2 and 3) for storing garbage, and the front door 4 is opened to remove the collected dust. It has a structure that can be recovered.

  In addition, a camera unit 8 is disposed above the main body 2 as an image pickup means for a waste dumper. The camera unit 8 is attached to a wall or the like above the main body 2 by an attachment unit 10 and captures a face image of a waste dumper. The main body 2 and the camera unit 8 are electrically connected by a camera connection cable 12 so that a face image captured by the camera unit 8 can be transmitted to the main body 2.

  A LAN cable 13 is connected to the side surface of the main body 2 and is connected to a server 51 for recording and storing a face image via a LAN (Local Area Network) 50 as described later (see FIG. 6). The main body 2 transmits to the server 51 via the LAN 50 and records the face image data of the waste dumper who dumped garbage other than plastic that is not a collection target despite the warning.

  Next, the internal structure of the main body 2 will be described with reference to FIGS. A circuit board 16 on which a circuit for controlling each function of the trash can 1 is mounted is attached to the back side behind the movable lid 3 so as to face the back side of the main body 2. The circuit board 6 is electrically connected to each of the camera connection cable 12, the sensor connection cable 11, and the LAN cable 13 drawn into the main body 2 through the insertion holes 31a, 31b, and 31c via connectors 30a, 30b, and 30c. It is connected to the. Further, a power cable 29 is drawn from an insertion hole 31d on the back surface of the main body 2, and power is supplied to the circuit board 6 through the connector 30d. The circuit board 6 and the cables 11, 12, 13, and 29 are disposed and disposed on the back side of the main body 2, and are separated from certain parts such as the movable plate 26 and the storage box by a shielding plate 27 c parallel to the back surface. Yes. The power supply to the camera unit 8 and the weight sensor 7 is performed via the camera connection cable 12 and the sensor connection cable 11, respectively.

  The movable lid 3 is pivotally attached to the first motor 18 held by the first motor holding portion 19 provided at the upper left portion of the main body 2 at the rotation shaft portion, and further, the first holding is on the opposite side of the pivoted portion. The shaft 20 is attached to be inserted into a first bearing 21 provided in the upper right part of the main body 2. The first motor 18 is electrically connected to the circuit board 16 via a wiring (not shown), and is driven by a predetermined amount in either direction in accordance with an instruction signal from the circuit board 16 to open or close the movable lid 3. To do.

  At the bottom of the main body 2, an upper surface is opened, and a garbage storage box 28 partitioned into a first storage portion 28a and a second storage portion 28b by a partition 28c provided in the vertical direction is provided. The first and second storage units 28a and 28b are provided for sorting based on whether or not the discarded garbage type is a plastic to be collected. The first storage portion 28a stores plastic, and the second storage portion 28b stores other garbage. The storage box 28 can be pulled out by opening the front door 4, whereby the waste collected in the first and second storage portions 28 a and 28 b can be collected. Instead of using the storage box 28 provided with the two storage units as in the present embodiment, two storage boxes having about half the size may be used.

  A flat plate-shaped movable plate 26 is provided above the dust storage box 28 so as to cover the openings of the first and second storage portions 28a, 28b. The movable plate 26 is a bottom plate of the holding storage chamber 55 located immediately inside the garbage input port 33, and the dumped garbage is temporarily stored in the holding storage chamber 55. The movable plate 26 is pivotally attached to the second motor 23 held by the second motor holding part 22 provided in the right center part of the main body 2 at the center part of the side surface, and is further on the opposite side of the pivoted part. Since the second holding shaft 24 is attached so as to be inserted into the second bearing 25 provided in the upper right portion of the main body 2, the second holding shaft 24 can be rotated around a horizontal axis that bisects the main surface. The second motor 23 is electrically connected to the circuit board 16 via a wiring (not shown), and is driven by a predetermined amount in any direction in accordance with an instruction signal from the circuit board 16, thereby moving the movable plate 26, It can be made to incline toward any one of the 1st accommodating part 28a mentioned above and the 2nd accommodating part 28b. Therefore, the dust on the movable plate 26 can be sorted and stored in the first storage portion 28a or the second storage portion 28b based on the dust type identified by the plastic detector 17 described later. For this reason, even if the waste dumper does not follow the warning and dumps the waste other than plastic, the waste can be sorted and stored, so that the collection efficiency of the waste can be improved. Similarly to the back side, the side surfaces are provided with shielding plates 27a and 27b to partition the first and second motors 18 and 23 and the first and second bearings 21 and 25.

  On the back side behind the movable plate 26, there is provided a plastic detector 17 for identifying whether or not the garbage type of the holding storage chamber 55 is plastic. The plastic detector 17 divides the near-infrared lamps 17b and 17b that irradiate the analysis target garbage with near-infrared rays and the light reflected from the dust when the lamp emits light, and analyzes the reflection spectrum to analyze the plastic. Or a spectroscopic analyzer 17a for determining whether or not. The plastic detector 17 is placed on a support plate 32 on the back side of the shielding plate 27c. From the opening of the shielding plate 27c, the light emitting surfaces of the near infrared lamps 17b and 17b and the condensing lens of the spectroscopic analyzer 17a. Is exposed. Although not shown, the plastic detector 17, the lamp 5, and the speaker 6 are electrically connected to the circuit board 16 via wiring.

  Next, the electrical configuration and function of the trash can 1 will be described with reference to FIG. The weight sensor 7 functions as a person detection unit, detects a weight of a predetermined amount or more when a person is placed, and notifies the main controller 35 of the weight. The first motor 18 functions as a driving unit for the movable lid 3. When the main control unit 35 receives notification that the weight sensor 7 has detected a person, the main control unit 35 sends an instruction signal to the first motor 18 to open the movable lid 3. On the other hand, when the weight sensor 7 no longer detects a person, an instruction signal is sent to the first motor 18 and the movable lid 3 is closed, assuming that the waste disposal has been completed. The movable lid 3 is also opened and closed when garbage other than price ticks is discarded as described later.

  The plastic detector 17 functions as a garbage type identification unit, identifies whether or not the garbage in the reserved storage chamber 55 is a plastic to be collected, and notifies the main control unit 35 of it. When the garbage type is plastic, the main control unit 35 drives the second motor to incline the movable plate 26 to drop the garbage into the first storage unit 28a. If the garbage type is not plastic, the lamp 5 is turned on and the sound of the warning message is output to the speaker 6. The warning message may be, for example, "The garbage you throw away is not plastic. Please remove it immediately." The lamp 5 is preferably red so that it stands out. In this way, by giving a warning to the garbage dumper who dumped the garbage that is not the collection target, the garbage dumper can know that the garbage dumped before the face image is recorded is not the collection target. Note that the warning message may be output only once or may be repeated a predetermined number of times. The lamp 5 is preferably turned on while a warning message is being output.

  The timer 26 starts timing when the plastic detector 17 identifies a garbage type other than plastic. When the timer 26 expires, the main control unit 35 sends an instruction signal to the first motor 18 so as to close the movable lid 3. Further, when garbage other than plastic is discarded and not removed, an instruction signal is sent to the second motor 23 to incline the movable plate 26 toward the second storage portion 28b, and stored in the image memory 37. The face image data of the waste dumper is read out and transmitted to the server 51 via the communication processing unit 38 and recorded. The second motor 23 is a driving means for driving the movable plate 26 and functions together with the movable plate 26 as a dust sorting means for sorting the garbage into the corresponding storage units 28a and 28b according to an instruction signal from the main control unit 35.

  Although the detailed configuration will be described later, the camera unit 8 captures the face image of the waste dumper and transmits the face image data to the main control unit 35. The main control unit 35 transmits an instruction signal to start imaging to the camera unit 8 when the weight sensor 7 detects a person. The camera unit 8 may capture a plurality of face images in consideration of failure shooting, or may capture images as moving images for a predetermined time.

  The image memory 37 is a volatile memory for temporarily storing the face image data captured by the camera unit 8 and is realized by, for example, an SDRAM (Synchronous Dynamic RAM). The main control unit 35 temporarily stores the face image data received from the camera unit 8 in the image memory 37, and deletes the face image data from the image memory 37 after a series of processing ends as will be described later.

  The communication processing unit 38 is a communication unit that processes communication with the server 51 connected via the LAN 50 with the LAN cable 13 as shown in FIG. When the garbage dumper dumps garbage that is not to be collected, the main control unit 35 issues a warning with the lamp 5 and the speaker 6, and when the garbage is not removed from the waste bin after a predetermined time, the main control unit 35 stores the garbage in the image memory 37. The face image of the waste dumper is transmitted to the server 51 via the communication processing unit 38 and recorded. The server 51 is connected to a plurality of recycle bins 1 and records face images transmitted from the recycle bins on a hard disk or the like to manage them collectively. An ID for recognition is assigned to each trash box, and the server 51 stores the face image in association with this ID and the date / time when the image was taken. Therefore, it is possible to identify a waste dumper who did not properly sort and give guidance on sorting of waste, and to improve manners of sorting. Note that this embodiment is based on the premise that a trash can is installed indoors. However, when installing outdoors, it is difficult to establish an environment for connecting to the LAN 50 using the LAN cable 13. It is desirable to apply a LAN connection environment via a LAN connection or a power line.

  The main control unit 35 performs overall control of the operation of the trash box 1, transmits instruction signals to the respective units, and conversely receives signals from the respective units to perform appropriate processing. The main control unit 35 is realized by a processor such as a CPU, and operates by reading a program from a main ROM 39 which is a nonvolatile memory such as a flash ROM.

  Next, the configuration and function of the camera unit 8 will be described. As shown in FIG. 5, the camera unit 8 has a configuration of a digital camera. A photographing lens 9 is arranged on the front surface of the camera unit 8 as is well known. The photographing lens 9 is moved in the optical axis direction by a lens driving unit 40 including a motor, a motor driver, a driving mechanism, and the like. The lens driving unit 40 is driven by an instruction signal from the photographing operation control unit 47 based on a setting signal from the main control unit 35, but is driven after the lens position is adjusted after the trash box 1 is installed. There is no. A mechanical shutter 41 that opens and closes the photographing optical path is disposed behind the photographing lens 3 in the optical axis direction. When the photographing operation control unit 47 receives a photographing instruction signal from the main control unit 35, the photographing operation control unit 47 opens and closes the mechanical shutter 41 at an appropriate timing.

  A CCD 42 is disposed behind the mechanical shutter 41 in the optical axis direction as an image sensor. The CCD 42 converts subject light that has passed through the photographing lens 9 and is imaged on the light receiving surface into an electrical imaging signal, and performs CDS (correlated double sampling) based on a transfer pulse supplied from the drive circuit 44. Output to the circuit 43. Note that a CMOS sensor may be used as the image sensor instead of the CCD 42.

  The CDS circuit 43 is driven based on the drive pulse output from the drive circuit 44, reduces noise in the image pickup signal output from the CCD 42, and outputs it to the A / D conversion circuit 45. The driving pulse of the driving circuit 44 is synchronized with the pulse signal from the photographing operation control unit 47. The A / D conversion circuit 45 converts the input analog imaging signal into digital image data and outputs the digital image data to the imaging operation control unit 47. The image data is subjected to various image processing and output to the compression / decompression unit 46. The compression / decompression unit 46 compresses the input image data and converts it into a data format such as JPEG, and the photographing operation control unit 47 reads out the compressed image data and transmits it to the main control unit 35.

  Next, the effect of the trash can 1 is demonstrated using FIG. When the weight sensor detects a person (ON) (st 1), the main control unit 35 sends an instruction signal to the camera unit 8 to photograph the face image of the waste dumper, and temporarily receives the received face image data to the image memory 37. (St2). Thereafter, an instruction signal is sent to the first motor 18 to open the movable lid 3 (st3). Thereafter, when the weight sensor no longer detects a person (st4), it is assumed that the waste has been discarded, and an instruction signal is sent to the first motor 18 to close the movable lid 3 (st5).

  Thereafter, the type of garbage dumped by the plastic detector 17 is identified. When the garbage type is plastic (st6), an instruction signal is sent to the second motor 23, the movable plate 26 is tilted toward the first storage portion 28a, and the waste is stored in the first storage portion 28a (st15). The image data is deleted from the image memory 37 (st16).

  On the other hand, if the garbage type is other than plastic (st6), an instruction signal is sent to the first motor 18 so that the dust can be removed, the movable lid 3 is opened (st7), and the timer starts counting (st8). ). Until the timer expires, the lamp 6 and the speaker continue to warn the waste dumper (st9, st10). After the timer expires, an instruction signal is sent to the first motor 18 to close the movable lid 3 (st11), and the type of dust is identified again by the plastic detector 17 to check whether there is any dust other than plastic (st12). When the waste dumper removes garbage other than plastic according to the warning, an instruction signal is sent to the second motor 23 to incline the movable plate 26 toward the first storage portion 28a, and store the waste in the first storage portion 28a. Then, the face image data is deleted from the image memory 37 (st16).

  On the other hand, if the waste dumper has left garbage other than plastic without following the warning, an instruction signal is sent to the second motor 23 to incline the movable plate 26 toward the second storage portion 28b to remove the waste. The face image data is stored in the second storage unit 28b (st13), read from the image memory 37, transmitted from the communication processing unit 38 to the server 51, and recorded (st14). Thereafter, the face image data is deleted from the image memory 37 (st16).

  Such a trash box 1 can improve manners of the waste dumper, improve the collection efficiency of the trash, and promote trash separation. In the present embodiment, the weight sensor 7 is used as the person detecting means, but the present invention is not limited to this. For example, a photoelectric sensor used in an automatic door or the like can be used. Further, a lid opening / closing switch may be provided in the trash bin without using the person detecting means.

  In the present embodiment, the camera unit 8 is an accessory of the trash box 1, but can also be configured as independent ones. In this case, the camera unit is directly connected to the server via the network and transmits a face image. On the other hand, the recycle bin notifies the server whether or not it is a waste dumper who did not follow the warning and did not follow the warning. Save and delete if not.

  Furthermore, in the present embodiment, the collection target of the trash can 1 is plastic, but many kinds of materials such as metal may be used. For example, if the object is metal, it is necessary to use a metal detector instead of the plastic detector 17. The shape of the trash can 1 is not limited to this embodiment, and may be a generally used shape such as a cylindrical shape.
