Description

本発明は、廃棄物収容装置に関する。   The present invention relates to a waste container.

例えば、特許文献1には、使用済みの生理用品などを廃棄するのに適した廃棄物収容装置(特許文献1では「ごみ箱」と表記)が開示されている。この廃棄物収容装置は、収容部と、その上部に取り外し可能に設けられた収容部カバー部材とを備えてなる。収容部カバー部材は、使用済み生理用品等の廃棄物を投入する投入口が上面に設けられていると共に、該投入口を開閉する蓋部材を有している。蓋部材は、側面視で略L字状をなす外蓋部(特許文献1における「蓋部材4」に相当)と内蓋部(特許文献1における「受け皿5」に相当)を備え、全閉時は外蓋部が投入口を覆い、全開時は内蓋部が投入口を覆うように、外蓋部と内蓋部との境界部付近が投入口の周囲の枠部に軸支されている。すなわち、この蓋部材は、使用済み生理用品等の廃棄物を廃棄する際の開口時においても、投入口を内蓋部が覆うようになっており、使用者が既に廃棄された収容部内の廃棄物(使用済み生理用品等)を見て不快に感じることを防止できる利点がある。蓋部材は、駆動源としての電動モータと該電動モータの回転を伝達するギヤ機構とを備えた回転駆動部によって回転動作するアーム(特許文献1では「リンク部材81」)を介して開閉される。また、収容部カバー部材には、人の手等の接近を検知するセンサ(赤外線センサ等)が設けられており、このセンサの検知信号に基づいて電動モータが駆動する。   For example, Patent Document 1 discloses a waste container device (indicated as “trash box” in Patent Document 1) suitable for discarding used sanitary products and the like. This waste container includes a container and a container cover member that is detachably provided on the container. The accommodating portion cover member is provided with an inlet on the upper surface for introducing waste such as used sanitary goods, and has a lid member for opening and closing the inlet. The lid member is provided with an outer lid portion (corresponding to “lid member 4” in Patent Document 1) and an inner lid portion (corresponding to “Tray 5” in Patent Document 1) that are substantially L-shaped in a side view, and is fully closed The outer lid part covers the inlet, and when fully opened, the inner lid part covers the inlet, and the boundary between the outer lid and inner lid is pivotally supported by the frame around the inlet. Yes. In other words, this lid member is configured so that the inner lid covers the insertion port even when opened when discarding wastes such as used sanitary products, and the user discards the waste in the storage unit that has already been discarded. There is an advantage that it is possible to prevent an object (such as a used sanitary product) from being uncomfortable. The lid member is opened and closed via an arm (“link member 81” in Patent Document 1) that rotates by a rotation drive unit that includes an electric motor as a drive source and a gear mechanism that transmits the rotation of the electric motor. . In addition, the housing cover member is provided with a sensor (infrared sensor or the like) that detects the approach of a human hand or the like, and the electric motor is driven based on a detection signal of the sensor.

特許第4005694号公報Japanese Patent No. 40056494

特許文献1の技術では、センサが人の手等の接近を検知すると、その信号が電動モータに送信され、電動モータの駆動力がギヤ機構を介してアーム(リンク部材)に伝達され、アーム(リンク部材)の回転によって蓋部材を押圧して自動的に開放動作させる。蓋部材は、上記のように外蓋部と内蓋部が略L字状に形成されているため、全開時には、外蓋部が側面視で90度に近い起立姿勢となり、内蓋部は略水平に近い姿勢となる。この状態で利用者は、内蓋部上に使用済み生理用品等のごみを載せる。その後、閉鎖動作する際には、電動モータが逆転駆動する。それにより、アーム(リンク部材)は原位置に戻るため、蓋部材はその自重により閉じていく。この閉鎖動作時において、内蓋部が投入口から離れるように略水平姿勢から下方に向かって回転して倒立姿勢になっていき、その過程で内蓋部上のごみは、収容部内に落下する。   In the technique of Patent Document 1, when the sensor detects the approach of a human hand or the like, the signal is transmitted to the electric motor, and the driving force of the electric motor is transmitted to the arm (link member) via the gear mechanism. The lid member is pressed by the rotation of the link member) to automatically open. As described above, since the outer lid portion and the inner lid portion are formed in a substantially L shape as described above, when the lid member is fully opened, the outer lid portion is in a standing posture close to 90 degrees in side view, and the inner lid portion is substantially The posture is almost horizontal. In this state, the user places garbage such as used sanitary goods on the inner lid. Thereafter, when the closing operation is performed, the electric motor is reversely driven. As a result, the arm (link member) returns to the original position, and the lid member is closed by its own weight. During this closing operation, the inner lid portion rotates downward from a substantially horizontal posture so as to move away from the inlet, and in the process, dust on the inner lid portion falls into the accommodating portion. .

上記のように蓋部材は自重により閉じるものであるが、閉鎖時に外蓋部が投入口に勢いよく当接すると異音を生じる。この問題を解決するために、軸部に緩衝装置を別途設けることも考えられるが、特許文献1ではその点についての明記はなく、また、別途の緩衝装置を設けると構造が複雑化する。その一方、電動モータやギヤ機構に塗布されている潤滑剤は、特に冬季等の低温環境において粘性が高くなり、閉鎖動作時の最終位置において、アーム(リンク部材)が原位置に戻りきらず、蓋部材の外蓋部と投入口回りの枠部との間に隙間が生じてしまう場合がある。   As described above, the lid member closes due to its own weight, but when the outer lid portion vigorously abuts the insertion port when closed, an abnormal noise is generated. In order to solve this problem, it is conceivable to separately provide a shock absorber in the shaft portion. However, Patent Document 1 does not specify this point, and if a separate shock absorber is provided, the structure becomes complicated. On the other hand, the lubricant applied to the electric motor and gear mechanism becomes highly viscous especially in a low temperature environment such as winter, and the arm (link member) does not return to the original position at the final position during the closing operation, and the lid There may be a gap between the outer lid of the member and the frame around the slot.

本発明は上記に鑑みなされたものであり、蓋部材の閉鎖動作時、該蓋部材が勢いよく閉じて大きな音が発生したり、逆に該蓋部材が完全に閉じなかったりする事態を防止できる廃棄物収容装置を提供することを課題とする。   The present invention has been made in view of the above, and can prevent a situation in which the lid member closes vigorously when the lid member is closed and a loud sound is generated or the lid member is not completely closed. It is an object to provide a waste container.

In order to solve the above-described problem, the waste container of the present invention includes a lid member that opens and closes a charging port provided in an upper part of the container,
In the waste container including the opening / closing mechanism for opening / closing the lid member,
The lid member includes an outer lid portion and an inner lid portion that are substantially L-shaped in a side view, and the outer lid portion covers the inlet when fully closed, and the inner lid portion is the inlet when fully opened. It is rotatably arranged so as to cover the mouth,
The opening / closing mechanism includes an arm that can contact the lid member, a rotation driving unit that includes a connecting shaft that is connected to a base end portion of the arm, and a control unit that controls the rotation driving unit. Become
The control unit is
During the opening operation of the lid member, the rotation drive unit is driven to rotate forward, the lid member is pressed in the opening direction by the arm, and the inner lid unit is operated to a fully opened position covering the insertion port,
During the closing operation of the lid member, the rotation drive unit is driven in reverse rotation with a rotational torque smaller than the rotational torque when the lid member rotates in its closing direction by its own weight, and the lid member is closed while contacting the arm. Actuate to slow down the closure speed of the lid member; and
After the lid member is fully closed, the reverse drive of the rotation drive unit is continued and the arm is separated from the lid member.

前記制御部は、前記外蓋部が前記投入口を覆う全閉位置よりも所定角度手前において、前記回転駆動部を一時的に正転駆動させた後、再度逆転駆動させるように制御する構成であることが好ましい。   The control unit is configured to control so that the rotation driving unit is temporarily forward-rotated and then reverse-rotated again after a predetermined angle before the fully-closed position where the outer lid part covers the insertion port. Preferably there is.

前記蓋部材は、前記内蓋部が前記投入口を覆う全開時に、側面視で、前記外蓋部が垂直よりも前記投入口寄りに傾斜した姿勢となるように、前記外蓋部と前記内蓋部とのなす角の角度が設定されていることが好ましい。   The lid member and the inner lid portion are arranged so that the outer lid portion is inclined closer to the inlet port than in the vertical direction in a side view when the inner lid portion is fully opened to cover the inlet port. It is preferable that the angle formed by the lid portion is set.

前記収容部の上部に、人の手等の接近を検知する検知装置が配設されており、
前記制御部は、前記検知装置から出力される検知信号を受信すると、前記回転駆動部を駆動させる構成であることが好ましい。
A detection device for detecting the approach of a human hand or the like is disposed on the upper portion of the housing portion,
Preferably, the control unit is configured to drive the rotation driving unit when receiving a detection signal output from the detection device.

前記開閉動作機構には、外部の任意の装置との間で通信可能な通信部が設けられており、前記開閉動作機構の動作状況を通信可能である構成とすることが好ましい。   It is preferable that the opening / closing operation mechanism is provided with a communication unit capable of communicating with an arbitrary external device, and the operation status of the opening / closing operation mechanism can be communicated.

本発明によれば、蓋部材の閉鎖動作時は、蓋部材が自重で閉鎖方向に回転する際の回転トルクよりも小さな回転トルクで回転駆動部を逆転駆動させ、蓋部材をアームに接触させつつ閉鎖動作させる。そのため、閉鎖時のみに使用される別途の緩衝機構を設けることなく、すなわち簡易な構成で、蓋部材の閉鎖速度を遅動させることができ、蓋部材が急速に閉まらないようにできる。その結果、全閉時において、外蓋部が投入口回りの枠部に勢いよく接触して異音を発生したりすることを抑制できる。   According to the present invention, during the closing operation of the lid member, while the lid member is driven in reverse by a rotational torque smaller than the rotational torque when the lid member rotates in the closing direction by its own weight, the lid member is brought into contact with the arm. Close operation. Therefore, the closing speed of the lid member can be delayed without providing a separate buffer mechanism that is used only at the time of closing, that is, with a simple configuration, and the lid member can be prevented from closing rapidly. As a result, when the cover is fully closed, it is possible to prevent the outer lid portion from vigorously contacting the frame portion around the inlet and generating abnormal noise.

また、蓋部材の全閉時以降、回転駆動部の逆転駆動を継続させ、アームを蓋部材から離間させるよう制御される。このため、閉鎖時において、蓋部材がアームによって開放方向に力を受けることがない。その結果、回転駆動部を構成する電動モータやギヤ機構に塗布されている潤滑剤が、例えば冬季等の低温環境において粘性が高くなったとしても、そのことを要因として、蓋部材が閉まり切らないという問題が発生しない。   Further, after the lid member is fully closed, the rotation drive unit is controlled to continue the reverse rotation so that the arm is separated from the lid member. For this reason, at the time of closing, the lid member does not receive a force in the opening direction by the arm. As a result, even if the lubricant applied to the electric motor and gear mechanism constituting the rotation drive unit becomes highly viscous in a low-temperature environment such as winter, the lid member does not completely close due to that. Does not occur.

また、外蓋部が全閉位置よりも所定角度手前において、回転駆動部を一時的に正転駆動させる構成とすることにより、蓋部材の閉鎖動作にブレーキがかかることになり、蓋部材が、投入口回りの枠部に当接する際の異音の発生をより確実に防止できる。   In addition, when the outer lid part is configured to temporarily rotate the rotation drive part forward by a predetermined angle before the fully closed position, the closing operation of the lid member is braked. It is possible to more reliably prevent the generation of abnormal noise when contacting the frame portion around the insertion port.

以下、図面に示した実施形態に基づき本発明をさらに詳細に説明する。本実施形態の廃棄物収容装置1は、図1に示すように、収容部10と、その上部に取り付けられる収容部カバー部材20とを有している。具体的には、収容部10は、上部11が開口した所定の高さを有する平面視で略方形の箱状に形成されている(図1、図4及び図5参照)。その縦、横、奥行き及び高さの各寸法は、廃棄物(使用済み生理用品等)の収容量や設置場所等を考慮して適宜に設定される。   Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings. As shown in FIG. 1, the waste container 1 of the present embodiment includes a container 10 and a container cover member 20 attached to the upper part. Specifically, the accommodating portion 10 is formed in a substantially rectangular box shape in plan view having a predetermined height with the upper portion 11 opened (see FIGS. 1, 4, and 5). The vertical, horizontal, depth, and height dimensions are appropriately set in consideration of the amount of waste (used sanitary products, etc.) accommodated and the installation location.

一方、収容部カバー部材20は、図4及び図5に示すように、下部21が開口し、平面視で略方形に形成され、収容部10の上部11の開口を被覆するように装着される。具体的には、収容部カバー部材20の正面部27及び背面部28の下部付近の内面において、内方に突出する突起22,22及び23,23が、それぞれ上下に所定間隔をおいて一対ずつ形成されており、正面部27の一対の突起22,22間及び背面部28の一対の突起23,23間に、収容部10の上縁部において外方に突出するフランジ部12,13がそれぞれ係合し、それにより、両者は着脱可能に連結されるようになっている。   On the other hand, as shown in FIGS. 4 and 5, the housing portion cover member 20 is attached so that the lower portion 21 is open, is formed in a substantially square shape in plan view, and covers the opening of the upper portion 11 of the housing portion 10. . Specifically, a pair of protrusions 22, 22 and 23, 23 projecting inwardly on the inner surfaces of the housing portion cover member 20 near the lower portions of the front portion 27 and the rear portion 28, respectively, at a predetermined interval in the vertical direction. Flange portions 12 and 13 are formed between the pair of projections 22 and 22 of the front portion 27 and between the pair of projections 23 and 23 of the back surface portion 28 and project outward at the upper edge portion of the housing portion 10. Engage, thereby both being detachably connected.

収容部カバー部材20は、図2に示すように、その上面部26に、ごみを投入するための開口である投入口24が形成されている。なお、上面部26は、本実施形態では、背面部28側から正面部27側に向かうに従って、若干下方に傾斜する傾斜面状に形成されているが、これはあくまで一例であり、略水平面状に形成されていてもよい。投入口24は、正面部27と上面部26との境界付近から、背面部28に至る前までの範囲で、平面視で略四角形に開口形成されており、蓋部材30は、この投入口24を開口又は閉鎖するために配設される。   As shown in FIG. 2, the container cover member 20 has a top surface 26 formed with a loading port 24 that is an opening for loading garbage. In the present embodiment, the upper surface portion 26 is formed in an inclined surface shape that slightly inclines downward from the back surface portion 28 side toward the front surface portion 27 side. However, this is merely an example, and is substantially horizontal. It may be formed. The insertion port 24 is formed in an approximately rectangular shape in plan view from the vicinity of the boundary between the front portion 27 and the upper surface portion 26 to before reaching the back surface portion 28, and the lid member 30 is formed of the insertion port 24. Arranged to open or close.

蓋部材30は、図2、図4及び図5に示すように、側面視で略L字状をなすように形成された外蓋部31と内蓋部32とを備えている。蓋部材30は、全閉時では、外蓋部31が投入口24を覆った状態になり、全開時すなわち廃棄物を投入するタイミングでは、内蓋部32が投入口24を覆った状態になるように、外蓋部31と内蓋部32との境界部33付近が投入口24の周囲の枠部261よりも背面部28寄りに軸支されて配設される。より詳しく説明すると、蓋部材30には、外蓋部31と内蓋部32との境界部33付近の左右に後方に突出する突片35を有すると共に、各突片35に外方に突出する軸部35aがそれぞれ設けられており、各軸部35aが、収容部カバー部材20の上面部26の裏面に下方に突出するように左右に所定間隔をおいて一対設けられた軸受用片25の軸受孔25aに挿通され、これにより、該軸部35aを中心として、収容部カバー部材20に対して回動可能に設けられている。   As shown in FIGS. 2, 4, and 5, the lid member 30 includes an outer lid portion 31 and an inner lid portion 32 that are formed in a substantially L shape in a side view. When the lid member 30 is fully closed, the outer lid portion 31 is in a state of covering the inlet 24, and when fully opened, that is, when the waste is introduced, the inner lid portion 32 is in a state of covering the inlet 24. As described above, the vicinity of the boundary portion 33 between the outer lid portion 31 and the inner lid portion 32 is pivotally supported closer to the back surface portion 28 than the frame portion 261 around the insertion port 24. More specifically, the lid member 30 has projecting pieces 35 that project rearward to the left and right in the vicinity of the boundary portion 33 between the outer lid section 31 and the inner lid section 32, and project outward from each projecting piece 35. Each of the shaft portions 35a is provided, and each of the shaft portions 35a has a pair of bearing pieces 25 provided at predetermined intervals on the left and right sides so as to protrude downward on the back surface of the upper surface portion 26 of the housing portion cover member 20. It is inserted in the bearing hole 25a, and is thereby provided so as to be rotatable with respect to the accommodating portion cover member 20 around the shaft portion 35a.

蓋部材30は、上記のように外蓋部31と内蓋部32とを備え、側面視で略L字状に形成されているが、全閉時において、外蓋部31が上面部26の枠部261に嵌まって隙間を生じることのないように、上面部26と同じく正面側ほど低くなる傾斜面状となり、全開時においては、内蓋部32が投入口24を覆う略水平位置となるようにするため、本実施形態では、外蓋部31と内蓋部32とのなす角、すなわち、図4に示した外壁部31の外表面の接線の延長線と内蓋部32の底壁部321の裏面の延長線とが交差する角θが、直角未満となるように形成している。それにより、全開時でも、外蓋部31は軸部35aを中心として略垂直姿勢とはならずに、正面側に傾いた姿勢となり、自重による閉鎖方向への回転トルクが作用しやすい。   The lid member 30 includes the outer lid portion 31 and the inner lid portion 32 as described above, and is formed in an approximately L shape in a side view. However, when the lid member 30 is fully closed, the outer lid portion 31 is formed on the upper surface portion 26. As with the upper surface portion 26, it has an inclined surface shape that becomes lower toward the front side so that it does not fit into the frame portion 261, and when fully opened, the inner lid portion 32 has a substantially horizontal position that covers the inlet 24. Therefore, in this embodiment, the angle formed by the outer lid portion 31 and the inner lid portion 32, that is, the extension line of the tangent to the outer surface of the outer wall portion 31 shown in FIG. 4 and the bottom of the inner lid portion 32. The angle θ at which the extended line on the back surface of the wall 321 intersects is formed to be less than a right angle. As a result, even when fully opened, the outer lid portion 31 does not take a substantially vertical posture with the shaft portion 35a as the center, but assumes a posture inclined to the front side, and rotational torque in the closing direction due to its own weight is likely to act.

これによって、廃棄物収容装置1の未使用時においては、蓋部材30は、図4に示すように、軸部35aを支点として下方向に回動することで、外蓋部31が収容部カバー部材20の投入口24の周囲の枠部261に当接して該投入口24を閉鎖する。   As a result, when the waste container 1 is not used, the lid member 30 rotates downward with the shaft portion 35a as a fulcrum as shown in FIG. The input port 24 is closed by contacting the frame portion 261 around the input port 24 of the member 20.

一方、廃棄物収容装置1の使用時、つまり、廃棄物収容装置1に廃棄物を捨てる場合においては、蓋部材30は、図2及び図5に示すように、軸部35aを中心として上方向に回動することで、外蓋部31が収容部カバー部材20の枠部261から離間して投入口24を開口状態にする。   On the other hand, when the waste container 1 is used, that is, when the waste is discarded in the waste container 1, the lid member 30 moves upward with the shaft portion 35 a as the center as shown in FIGS. 2 and 5. , The outer lid portion 31 is separated from the frame portion 261 of the housing portion cover member 20 to open the insertion port 24.

内蓋部32は、図3,図4及び図5に示すように、底壁321とその左右に設けられた側壁322,322とを備えており、その後端部が外蓋部31の後端部に接続されて一体に形成されている。蓋部材30の開口動作時は、蓋部材30が軸部35aを中心として上方向に回動することで、内蓋部32は図4の倒立状態から図5の略水平状態となるように前方に回動し、投入口24を下方から閉鎖する。この時、投入口24の枠部261の前縁部261aは、背面部28方向に突出形成されているため、内蓋部32の底壁321の先端縁321aが前縁部261aの下面に当接し、該投入口24を下方から閉鎖する。   As shown in FIGS. 3, 4, and 5, the inner lid portion 32 includes a bottom wall 321 and side walls 322 and 322 provided on the left and right sides of which the rear end portion is the rear end of the outer lid portion 31. It is connected to the part and formed integrally. When the lid member 30 is opened, the lid member 30 rotates upward about the shaft portion 35a, so that the inner lid portion 32 moves forward from the inverted state of FIG. 4 to the substantially horizontal state of FIG. And the closing port 24 is closed from below. At this time, since the front edge portion 261a of the frame portion 261 of the insertion port 24 is formed to protrude in the direction of the back surface portion 28, the leading edge 321a of the bottom wall 321 of the inner lid portion 32 contacts the lower surface of the front edge portion 261a. Then, the inlet 24 is closed from below.

その結果、蓋部材30の外蓋部31が全開時は、内蓋部32が投入口24を覆うことで目隠しとなり、外部からは収容部10に収容されている使用済み生理用品等の廃棄物(ごみ)が目に触れることがない。また、内蓋部32は左右の側壁322,322により補強された構造となっており、内蓋部32に載せられたごみが左右方向へ脱落するのを防止する。   As a result, when the outer lid portion 31 of the lid member 30 is fully opened, the inner lid portion 32 is blindfolded by covering the insertion port 24, and wastes such as used sanitary goods housed in the housing portion 10 from the outside. (Garbage) is not visible. Further, the inner lid portion 32 has a structure reinforced by the left and right side walls 322 and 322, and prevents the dust placed on the inner lid portion 32 from falling off in the left-right direction.

また、内蓋部32の内側の表面には、図2及び図3に示すように、前後方向に向けて長い列状の突起321bが複数個、横並びに配設されている。これにより、複数個の突起321b,・・・,321bの表面に接触するごみの面積が少なくなるので、例えば接着性を有するごみが内蓋部32に載せられても、その表面に貼り付きにくくなる。   Further, as shown in FIGS. 2 and 3, a plurality of row-like protrusions 321 b extending in the front-rear direction are arranged side by side on the inner surface of the inner lid portion 32. Thereby, since the area of the dust which contacts the surface of the plurality of protrusions 321b,..., 321b is reduced, for example, even if dust having adhesiveness is placed on the inner lid portion 32, it is difficult to stick to the surface. Become.

なお、上述の収容部10、収容部カバー部材20、蓋部材30は、いずれも蓋部材30の開閉時に発生する音を小さくするため、ステンレス等の金属製よりも、ポリプロピレン等の合成樹脂製であることが好ましく、さらには抗菌性を付与した樹脂製とすることが望ましい。   In addition, in order to reduce the sound which generate | occur | produces at the time of opening and closing of the cover member 30, the above-mentioned accommodating part 10, the accommodating part cover member 20, and the cover member 30 are all made of synthetic resin such as polypropylene rather than metal such as stainless steel. It is preferable that the resin is made of a resin imparted with antibacterial properties.

廃棄物収容装置1には、図4及び図5に示すように、蓋部材30を自動開閉させる開閉動作機構40を設けている。開閉動作機構40は、回転駆動部41と制御部42とを有して構成される。回転駆動部41は、電動モータ411(ステッピングモータ)とギヤ機構412とを有して構成され、ギヤ機構412の連結軸412aにアーム44の基端部が連結される。また、該アーム44の先端部は、内蓋部32の裏側に当接可能に配設される(図4及び図5参照)。   As shown in FIGS. 4 and 5, the waste container 1 is provided with an opening / closing operation mechanism 40 that automatically opens and closes the lid member 30. The opening / closing operation mechanism 40 includes a rotation driving unit 41 and a control unit 42. The rotation drive unit 41 includes an electric motor 411 (stepping motor) and a gear mechanism 412, and the base end portion of the arm 44 is coupled to the coupling shaft 412 a of the gear mechanism 412. Further, the distal end portion of the arm 44 is disposed so as to be in contact with the back side of the inner lid portion 32 (see FIGS. 4 and 5).

図4に示すように、蓋部材30の外蓋部31の全閉時には、内蓋部32はその先端縁321aが下方を向いた略垂直な倒立姿勢になっている。この状態から蓋部材30を開く方向に動作させる際は、アーム44は図4において時計回りに回動するように制御される。すなわち、アーム44は、図4に示す実線の位置(T1)から回動して二点鎖線の位置(T2)で内蓋部32の裏側に接触し、蓋部材30の自重による閉じる方向への回転トルクに抗して図4の状態から図5の状態へ時計回りに回動し、それにより、蓋部材30を開口位置まで動作させる。   As shown in FIG. 4, when the outer lid portion 31 of the lid member 30 is fully closed, the inner lid portion 32 is in a substantially vertical inverted posture with the leading edge 321a facing downward. When the lid member 30 is moved from this state in the opening direction, the arm 44 is controlled to rotate clockwise in FIG. That is, the arm 44 rotates from the solid line position (T1) shown in FIG. 4 and contacts the back side of the inner lid part 32 at the two-dot chain line position (T2). 4 rotates from the state of FIG. 4 to the state of FIG. 5 against the rotational torque, thereby moving the lid member 30 to the open position.

その逆に、蓋部材30を閉じる方向に動作させる際は、アーム44は、図5の実線で示された位置(T3)から図4の実線で示された位置(T1)に至るまで反時計回りに回動するように制御される。蓋部材30は、全開位置において内蓋部32が略水平姿勢であるため、該蓋部材30は、軸部35aを中心として、常に図5の反時計回りに自重による回転トルクがかかっている。そのため、アーム44が反時計回りに回動する際には、蓋部材30はその内蓋部32が常にアーム44に接触しながら閉じる方向に動作していく。   On the contrary, when the lid member 30 is moved in the closing direction, the arm 44 counterclockwise from the position (T3) indicated by the solid line in FIG. 5 to the position (T1) indicated by the solid line in FIG. It is controlled to rotate around. Since the cover member 30 has the inner cover part 32 in a substantially horizontal posture at the fully opened position, the cover member 30 is always subjected to rotational torque due to its own weight in the counterclockwise direction of FIG. 5 around the shaft part 35a. Therefore, when the arm 44 rotates counterclockwise, the lid member 30 moves in a closing direction while the inner lid portion 32 always contacts the arm 44.

制御部42は、電動モータ411へ供給するパルス信号の送り間隔等を調整するコンピュータプログラムが設定された電子回路等が組み込まれた制御基盤から構成されている。なお、制御部42の機能についてはさらに後述する。また、符号45は乾電池であり、回転駆動部41の電動モータ411及び制御部42等に電気を供給する。   The control unit 42 is composed of a control board in which an electronic circuit or the like in which a computer program for adjusting a sending interval of a pulse signal supplied to the electric motor 411 is set is incorporated. The function of the control unit 42 will be further described later. Reference numeral 45 denotes a dry battery, which supplies electricity to the electric motor 411 and the control unit 42 of the rotation drive unit 41.

開閉動作機構40には、手等の接近を検知してその検知信号を制御部42に出力して電動モータ411の駆動を開始させる検知装置を備えることが望ましい。この検知装置は、例えば赤外線センサ43からなり、図1、図4及び図5に示すように、収容部カバー部材20の上面部26に窓部26aを設け、この窓部26aに対応するように配置される。これにより、利用者は廃棄物収容装置1に直接触れることなく、蓋部材30を開閉動作することができる。   The opening / closing mechanism 40 preferably includes a detection device that detects the approach of a hand or the like and outputs a detection signal to the control unit 42 to start driving the electric motor 411. The detection device includes, for example, an infrared sensor 43, and as shown in FIGS. 1, 4, and 5, a window portion 26a is provided on the upper surface portion 26 of the accommodating portion cover member 20, and the window portion 26a corresponds to the window portion 26a. Be placed. Accordingly, the user can open and close the lid member 30 without directly touching the waste container 1.

次に、蓋部材30の開閉動作させる制御部42の機能について図6のフロー図を参照して詳しく説明する。まず、廃棄物収容装置1の電源スイッチ(図示しない)をONすると、乾電池45,45から電力が供給される(ステップ10(S10))。それにより、赤外線センサ43の検知動作が開始される(ステップ11(S11))。この時点では、電動モータ411は駆動されず、蓋部材30の開閉動作は開始しない。   Next, the function of the controller 42 that opens and closes the lid member 30 will be described in detail with reference to the flowchart of FIG. First, when a power switch (not shown) of the waste container 1 is turned on, power is supplied from the dry batteries 45 and 45 (step 10 (S10)). Thereby, the detection operation of the infrared sensor 43 is started (step 11 (S11)). At this time, the electric motor 411 is not driven, and the opening / closing operation of the lid member 30 is not started.

次に、利用者が窓部26a付近に手をかざすと、赤外線センサ43により検知される(ステップ12(S12))。赤外線センサ43が手を検知すると、制御部42にその検知信号が送られ、それにより、制御部42から電動モータ411に駆動信号が供給される。つまり、電動モータ411にパルス信号が供給されて電動モータ411が回転し、この回転トルクがギヤ機構412を介して連結軸412aに伝達され、連結軸412aに連結されたアーム44によって蓋部材30を開く方向に正転駆動する。アーム44は、図4及び図5において時計回り(T1からT3に向かって変位する方向)に回動し、T2の位置に至ると、蓋部材30の内蓋部32の裏面に接触し、それ以降T3の位置に至るまで該内蓋部32を押圧し、軸部35aを中心として、その自重に抗して押し上げる(ステップ13(S13))。   Next, when the user holds his hand near the window portion 26a, the infrared sensor 43 detects it (step 12 (S12)). When the infrared sensor 43 detects a hand, the detection signal is sent to the control unit 42, whereby a drive signal is supplied from the control unit 42 to the electric motor 411. That is, a pulse signal is supplied to the electric motor 411 to rotate the electric motor 411, and this rotational torque is transmitted to the connecting shaft 412a via the gear mechanism 412, and the lid member 30 is moved by the arm 44 connected to the connecting shaft 412a. Drive forward in the opening direction. 4 and 5, the arm 44 rotates clockwise (in the direction of displacement from T1 to T3). When the arm 44 reaches the position of T2, the arm 44 comes into contact with the back surface of the inner lid portion 32 of the lid member 30. Thereafter, the inner lid portion 32 is pressed until reaching the position of T3, and is pushed up against its own weight around the shaft portion 35a (step 13 (S13)).

その結果、外蓋部31は内蓋部32と一体であるため、該外蓋部31は、その前方端部311が、収容部カバー部材20の投入口24を形成している枠部261の前縁部261aから離間し、図5に示すように、投入口24を開口していく。そして、内蓋部32の底壁321の先端縁321aが投入口24の枠部261の前縁部261aにその下方から当接し、それ以上回動できなくなる。この位置が全開位置(アーム44はT3の位置)となる。   As a result, since the outer lid portion 31 is integral with the inner lid portion 32, the outer lid portion 31 has a front end portion 311 of the frame portion 261 that forms the insertion port 24 of the housing portion cover member 20. The charging port 24 is opened away from the front edge 261a as shown in FIG. And the front-end edge 321a of the bottom wall 321 of the inner cover part 32 contact | abuts from the downward direction to the front edge part 261a of the frame part 261 of the insertion port 24, and it becomes impossible to rotate any more. This position is the fully open position (the arm 44 is at the position T3).

制御部42は、蓋部材30が全開位置に至ったならば、所定の設定時間、全開状態を保持するように制御する(ステップ14(S14))。すなわち、蓋部材30は、開口方向への回転トルクが付与されていない場合、自重により閉鎖方向に回転しようとするが、制御部42は、その自重による閉鎖方向への回転トルクに抗して、電動モータ411に供給するパルス信号を制御して、蓋部材30を所定の回転トルクで正転方向に付勢し、所定の設定時間、全開状態を保持させる。蓋部材30が全開状態のときは、内蓋部32が略水平姿勢となっているため、その間に、利用者は、使用済み生理用品等のごみを内蓋部32に載せる。   When the lid member 30 reaches the fully open position, the control unit 42 controls to maintain the fully open state for a predetermined set time (step 14 (S14)). That is, when the rotational torque in the opening direction is not applied, the lid member 30 tries to rotate in the closing direction due to its own weight, but the control unit 42 resists the rotational torque in the closing direction due to its own weight, By controlling the pulse signal supplied to the electric motor 411, the lid member 30 is urged in the normal rotation direction with a predetermined rotational torque, and kept fully open for a predetermined set time. When the lid member 30 is in the fully open state, the inner lid portion 32 is in a substantially horizontal posture, and during that time, the user places garbage such as used sanitary goods on the inner lid portion 32.

上記の所定の設定時間後、制御部42は、電動モータ411へのパルス信号の励磁方向を逆方向に切り替えて、電動モータ411を逆転駆動させる(ステップ15(S15))。これにより、アーム44は閉鎖方向(T3からT1に向かって変位する方向)に回動する。アーム44が閉鎖方向に回動すると、蓋部材30を開口状態で保持する力が小さくなるため、アーム44の動きに追従して、蓋部材30はその自重により閉鎖方向に回動しようとする。そこで、電動モータ411の逆転駆動時の回転トルクを、蓋部材30が自重で閉鎖方向に回転する際の回転トルクより小さくなるように、制御部42によってパルス信号のパルス間隔を適宜に調整するなどして制御する。それにより、蓋部材30は、内蓋部32の裏面が常にアーム44に接触した状態で閉鎖方向に回動することになり、蓋部材30の閉鎖速度は、アーム44に規制されるため、閉鎖時のみに使用される別途の緩衝機構を設けていないにも拘わらず、遅動することになる(ステップ16(S16))。   After the predetermined set time, the control unit 42 switches the excitation direction of the pulse signal to the electric motor 411 to the reverse direction to drive the electric motor 411 in reverse (step 15 (S15)). Thereby, the arm 44 rotates in the closing direction (direction displaced from T3 toward T1). When the arm 44 rotates in the closing direction, the force for holding the lid member 30 in the open state decreases, so that the lid member 30 tries to rotate in the closing direction by its own weight following the movement of the arm 44. Therefore, the control unit 42 appropriately adjusts the pulse interval of the pulse signal so that the rotational torque at the time of reverse driving of the electric motor 411 is smaller than the rotational torque when the lid member 30 rotates in its closing direction under its own weight. And control. Accordingly, the lid member 30 rotates in the closing direction with the back surface of the inner lid portion 32 always in contact with the arm 44, and the closing speed of the lid member 30 is regulated by the arm 44. Although there is no separate buffer mechanism used only for the time, it is delayed (step 16 (S16)).

上記のステップ16により、蓋部材30の閉鎖速度を遅動させることができ、それにより、蓋部材30の外蓋部31が投入口24を形成している枠部261に当接する際の接触音を低減できる。しかしながら、外蓋部31が枠部261に当接する際の力をより低減するため、蓋部材30の閉鎖動作時、外蓋部31が投入口24を覆う全閉位置よりも所定角度手前において、蓋部材30にブレーキをかける制御工程が設定されていることが好ましい。本実施形態では、外蓋部31が投入口24を覆う全閉位置(アーム44におけるT2位置)よりも所定角度手前(例えば、軸部35aを中心として投入口24からの開口角度が30度以下のいずれかの角度、好ましくは20度以下のいずれかの角度、より好ましくは10度以下のいずれかの角度)に至ったならば、制御部42は、電動モータ411へのパルス信号の励磁方向を正転方向に切り替えて、電動モータ411を一時的に正転駆動させるように制御する(ステップ17(S17))。   By the above step 16, the closing speed of the lid member 30 can be delayed, and thereby the contact sound when the outer lid portion 31 of the lid member 30 comes into contact with the frame portion 261 forming the insertion port 24. Can be reduced. However, in order to further reduce the force when the outer lid portion 31 comes into contact with the frame portion 261, during the closing operation of the lid member 30, a predetermined angle before the fully closed position where the outer lid portion 31 covers the insertion port 24, It is preferable that a control process for applying a brake to the lid member 30 is set. In the present embodiment, a predetermined angle before the fully closed position (T2 position in the arm 44) where the outer lid portion 31 covers the inlet 24 (for example, the opening angle from the inlet 24 around the shaft portion 35a is 30 degrees or less. ), Preferably any angle of 20 degrees or less, more preferably any angle of 10 degrees or less), the control unit 42 performs the excitation direction of the pulse signal to the electric motor 411. Is switched to the normal rotation direction, and the electric motor 411 is controlled to temporarily rotate forward (step 17 (S17)).

これにより、アーム44は、T2位置より所定角度T3側の位置において、一時的に開口方向に回転トルクが生じるため、該アーム44に内蓋部32が接触している蓋部材30の閉鎖動作にブレーキがかかる。但し、制御部42は、この際発生するアーム44が開口方向に回動する回転トルクとして、蓋部材30の自重による閉鎖方向への回転トルクよりも小さな回転トルクとなるように、すなわち、アーム44が再び蓋部材30を開口方向に回動させることができない回転トルクとなるように制御する。このステップ17により、蓋部材30の閉鎖動作が停止するか、停止に至らないまでも閉鎖速度が極めて遅くなる。   As a result, the arm 44 temporarily generates rotational torque in the opening direction at a position on the predetermined angle T3 side from the T2 position, so that the lid member 30 in which the inner lid portion 32 is in contact with the arm 44 is closed. The brake is applied. However, the control unit 42 is configured so that the rotation torque that the arm 44 generated at this time rotates in the opening direction is smaller than the rotation torque in the closing direction due to the weight of the lid member 30, that is, the arm 44. Is controlled so as to obtain a rotational torque that cannot rotate the lid member 30 in the opening direction again. By this step 17, even if the closing operation of the lid member 30 is stopped or not stopped, the closing speed becomes extremely slow.

ステップ17により、全閉位置の直前でブレーキがかかるが、蓋部材30が完全には停止せずに、閉鎖速度が極めて遅くなるような制御であれば、その状態のまますなわち電動モータ411を正転駆動させたまま蓋部材30を全閉位置に至らしめることも可能である。しかしながら、ブレーキをかける位置は、上記のように全閉位置の直前であり、蓋部材30の外蓋部31と枠部261との離間距離も非常に短くなった位置である。よって、その位置からは、再度、電動モータ411へのパルス信号の励磁方向を逆方向に切り替えて、電動モータ411を逆転駆動させた状態で、アーム44に内蓋部32を接触させながら閉鎖することが、より速やかな閉鎖動作のために好ましい(ステップ18(S18))。これにより、アーム44は内蓋部32に接しつつ図4の二点鎖線の位置(T2)まで回動する。   In step 17, the brake is applied immediately before the fully closed position, but if the control is such that the lid member 30 does not stop completely and the closing speed becomes extremely slow, the state is maintained, that is, the electric motor 411 is corrected. It is also possible to bring the lid member 30 to the fully closed position while being driven to roll. However, the position where the brake is applied is immediately before the fully closed position as described above, and the distance between the outer lid portion 31 of the lid member 30 and the frame portion 261 is also very short. Therefore, from that position, the excitation direction of the pulse signal to the electric motor 411 is switched to the reverse direction again, and the electric motor 411 is driven in reverse rotation, and the arm 44 is closed while contacting the inner lid portion 32. Is preferable for a quicker closing operation (step 18 (S18)). Thereby, the arm 44 rotates to the position (T2) of the two-dot chain line in FIG.

従って、蓋部材30は、ステップ17により、全閉位置の手前でブレーキがかかって閉鎖速度が遅くなり、その後もステップ18により、電動モータ411の抵抗を受けながら静かにゆっくり閉じていく。これにより、電動モータ411及びギヤ機構412に用いられた潤滑剤の抵抗が小さくなる夏季等の高温環境であっても、蓋部材30は閉鎖動作の最終位置において大きな接触音を生じることなく静かにゆっくり閉じることになる。   Therefore, the lid member 30 is braked before the fully closed position in step 17 and the closing speed is slowed down in step 17, and thereafter, in step 18, the lid member 30 is gently and slowly closed while receiving the resistance of the electric motor 411. Thereby, even in a high temperature environment such as summer when the resistance of the lubricant used in the electric motor 411 and the gear mechanism 412 is reduced, the lid member 30 is quietly generated without generating a large contact sound at the final position of the closing operation. It will close slowly.

本実施形態では、制御部42は、さらに、蓋部材30の全閉位置に至った後も、電動モータ411へのパルス信号の励磁方向を逆方向のまま継続するようパルス信号を供給し、つまり電動モータ411の逆転駆動を継続してアーム44を内蓋部32から離間させるよう制御する(ステップ19(S19))。   In the present embodiment, the control unit 42 further supplies a pulse signal so as to continue the excitation direction of the pulse signal to the electric motor 411 in the reverse direction even after reaching the fully closed position of the lid member 30. Control is performed so that the arm 44 is moved away from the inner lid portion 32 by continuing the reverse rotation of the electric motor 411 (step 19 (S19)).

これにより、蓋部材30は、図4の二点鎖線の位置(T2)から実線の位置(T1)まで回動し、アーム44が内蓋部32の底壁321から離間する。その結果、電動モータ411やギヤ機構412との間に隙間ができ、それらの力を受けることがなくなる。すなわち、蓋部材30の全閉時において、アーム44が図4の二点鎖線の位置(T2)までしか回動しない場合には、アーム44は全閉時においても常に内蓋部32に接していることになる。そのため、電動モータ411やギヤ機構412に用いられた潤滑剤の粘性が高くなる冬季等の低温環境において、その抵抗により、閉鎖動作の最終位置におけるアーム44の回動角度が不十分になった場合には、外蓋部31が枠部261に完全には当接せず、若干開いたままの状態になる可能性がある。しかしながら、本実施形態のようにステップ19の制御工程を設け、全閉時のアーム44の待機位置を上記のように内蓋部32から離間した位置(T1)に設定することにより、潤滑剤の粘性の高くなる低温環境においても外蓋部31を枠部261に確実に当接させ、投入口24を確実に閉鎖することができる。   As a result, the lid member 30 rotates from the position of the two-dot chain line (T2) in FIG. 4 to the position of the solid line (T1), and the arm 44 is separated from the bottom wall 321 of the inner lid portion 32. As a result, there is a gap between the electric motor 411 and the gear mechanism 412, and the force is not received. That is, when the arm 44 rotates only to the position of the two-dot chain line (T2) in FIG. 4 when the lid member 30 is fully closed, the arm 44 is always in contact with the inner lid portion 32 even when fully closed. Will be. Therefore, when the rotation angle of the arm 44 at the final position of the closing operation becomes insufficient due to the resistance in a low temperature environment such as winter when the viscosity of the lubricant used in the electric motor 411 and the gear mechanism 412 becomes high. There is a possibility that the outer lid part 31 does not completely abut against the frame part 261 and remains slightly open. However, the control process of step 19 is provided as in this embodiment, and the standby position of the arm 44 when fully closed is set to the position (T1) separated from the inner lid portion 32 as described above, so that the lubricant Even in a low temperature environment where the viscosity becomes high, the outer lid portion 31 can be reliably brought into contact with the frame portion 261 and the charging port 24 can be reliably closed.

なお、本実施形態に係る廃棄物収容装置1の開閉動作機構40には、外部の任意の装置との間で通信可能な通信部(図示せず)を設けることが好ましい。それにより、開閉動作機構40の動作状況を通信可能である。例えば、廃棄物収容装置1の開閉動作回数、電動モータ411の駆動電圧、あるいは、例えば蓋部材30に異物が挟まるなどして電動モータ411に過負荷がかかった際などにおける異常事態の発生などの動作情報を取り出す。これらの動作情報は、通信部から、廃棄物収容装置1の設置者、あるいは廃棄物収容装置1をレンタルしているレンタル事業者などの通信端末に送信できる。事業者は、この送信された動作情報に基づいて、異常情報であれば速やかに対応でき、また、例えば、電池の寿命や交換時期、廃棄物収容装置1の収容部10内に廃棄物が満杯になる時期(つまり、メンテナンス時期)などの予測もできる。   In addition, it is preferable to provide the communication part (not shown) which can communicate with the external arbitrary apparatuses in the opening / closing operation mechanism 40 of the waste container 1 which concerns on this embodiment. Thereby, the operation status of the opening / closing mechanism 40 can be communicated. For example, the number of opening / closing operations of the waste container 1, the driving voltage of the electric motor 411, or the occurrence of an abnormal situation such as when the electric motor 411 is overloaded due to foreign matter caught in the lid member 30, etc. Extract operation information. The operation information can be transmitted from the communication unit to a communication terminal such as an installer of the waste container 1 or a rental company that rents the waste container 1. Based on the transmitted operation information, the business operator can respond quickly if it is abnormal information. For example, the battery life or replacement time, and the waste storage device 1 is full of waste. It is possible to predict when it will become (that is, maintenance time).

また、収容部10には、予め設定した廃棄対象物と異なる異物を検知する異物検知装置を備えることができる。異物検知装置としては、金属に反応する検知器、あるいはその他のセンサを設ける。この場合、制御部42には、異物検知装置から出力される検知信号のデータを動作情報の一つとして通信部から発信する機能を付与する。これにより、異物検知装置は、例えば金属、爆発物などの異物が収容部10内に投入されたことを検出し、その検知信号を通信部から上記の通信端末に送信し、異物投入を速やかに知らせることができる。   In addition, the storage unit 10 can be provided with a foreign object detection device that detects a foreign object different from a preset disposal object. As the foreign matter detection device, a detector that reacts with metal or other sensors is provided. In this case, the control unit 42 is provided with a function of transmitting the detection signal data output from the foreign object detection device as one piece of operation information from the communication unit. As a result, the foreign object detection device detects that a foreign object such as a metal or explosive material has been introduced into the storage unit 10, and transmits the detection signal from the communication unit to the communication terminal to promptly insert the foreign object.
