　収容部１６の停止位置には、容器３を容器検査装置１へ供給する供給部１８と、容器３を検査する第１検査部２２、第２検査部２４、第３検査部２６を含む検査部２０と、第１排出部３０と、第２排出部３２とが設けられる。供給部１８には容器３を供給部１８に停止する収容部１６に順次送るスクリューコンベヤを備えていてもよい。検査部２０の各停止位置に停止した容器３は、容器３の中心軸の周りに自転しながら各種検査が実行される。 At the stop position of the accommodating unit 16, an inspection unit including a supply unit 18 for supplying the container 3 to the container inspection device 1, a first inspection unit 22, a second inspection unit 24, and a third inspection unit 26 for inspecting the container 3 are included. 20, a first discharge unit 30, and a second discharge unit 32 are provided. The supply unit 18 may include a screw conveyor that sequentially feeds the container 3 to the accommodating unit 16 that stops at the supply unit 18. The container 3 stopped at each stop position of the inspection unit 20 is subjected to various inspections while rotating around the central axis of the container 3.
　第１コンベヤ４０は、第１排出部３０で収容部１６から第１押出機構６０によって押し出された容器３を自立した状態で第１排出部３０から離れる第１方向Ｄ１へ搬送する。第１方向Ｄ１は、容器３の排出方向である。第２コンベヤ４２は、第２排出部３２で収容部１６から第２押出機構６２によって押し出された容器３を自立した状態で第２排出部３２から離れる第２方向Ｄ２へ搬送する。第２方向Ｄ２は、容器３の排出方向である。第１コンベヤ４０及び第２コンベヤ４２は、無端状のベルトを間欠または連続で循環駆動するベルトコンベヤーであることができ、本実施形態では連続で循環駆動する。第１コンベヤ４０及び第２コンベヤ４２は、その上面に容器３を自立した状態で搬送する。第１コンベヤ４０は第１排出部３０にある収容部１６の直下から周縁１４の外まで延び、第２コンベヤ４２は第２排出部３２にある収容部１６の直下から周縁１４の外まで延びる。 The first conveyor 40 conveys the container 3 extruded from the accommodating portion 16 by the first extrusion mechanism 60 by the first discharging unit 30 to the first direction D1 away from the first discharging unit 30 in a self-supporting state. The first direction D1 is the discharge direction of the container 3. The second conveyor 42 conveys the container 3 extruded from the accommodating section 16 by the second extrusion mechanism 62 by the second discharging section 32 to the second direction D2 away from the second discharging section 32 in a self-supporting state. The second direction D2 is the discharge direction of the container 3. The first conveyor 40 and the second conveyor 42 can be belt conveyors that intermittently or continuously circulate and drive the endless belt, and in the present embodiment, they are continuously circulated and driven. The first conveyor 40 and the second conveyor 42 convey the container 3 on its upper surface in a self-supporting state. The first conveyor 40 extends from directly below the accommodating portion 16 in the first discharging portion 30 to the outside of the peripheral edge 14, and the second conveyor 42 extends from directly below the accommodating portion 16 in the second discharging portion 32 to the outside of the peripheral edge 14.
　容器３が第１排出部３０に搬送されることで第１コンベヤ４０上に容器３が配置し、また容器３が第２排出部３２に搬送されることで第２コンベヤ４２上に容器３が配置する。本実施形態では第１排出部３０に停止する容器３の下まで第１コンベヤ４０は延在するが、第１コンベヤ４０を第１排出部３０に臨んで配置することで押し出された容器３を自立した状態で受け渡されればよく、例えば、第１コンベヤ４０が周縁１４の外側から第１方向Ｄ１に延びてもよい。第２コンベヤ４２も同様に例えば周縁１４の外側から第２方向Ｄ２に延びてもよい。 When the container 3 is conveyed to the first discharge unit 30, the container 3 is arranged on the first conveyor 40, and when the container 3 is conveyed to the second discharge unit 32, the container 3 is placed on the second conveyor 42. Deploy. In the present embodiment, the first conveyor 40 extends below the container 3 that stops at the first discharge unit 30, but the extruded container 3 is provided by arranging the first conveyor 40 facing the first discharge unit 30. It suffices if it is delivered in a self-supporting state. For example, the first conveyor 40 may extend from the outside of the peripheral edge 14 in the first direction D1. Similarly, the second conveyor 42 may extend in the second direction D2 from the outside of the peripheral edge 14, for example.
　第１コンベヤ４０及び第２コンベヤ４２は、容器３を自立したまま移動させるため、第１押出機構６０及び第２押出機構６２によって容器３が押されることで揺れて自立安定性を欠くことがある。第１コンベヤ４０上または第２コンベヤ４２上で容器３が転倒すると、容器検査装置１を緊急停止することになるため、容器検査装置１の単位時間当たりの処理能力が著しく低下する。よって、第１排出部３０（第２排出部３２）から第１コンベヤ４０（第２コンベヤ４２）への容器３の移動の安定化は重要である。 Since the first conveyor 40 and the second conveyor 42 move the container 3 in an independent manner, the container 3 may be pushed by the first extrusion mechanism 60 and the second extrusion mechanism 62 and shake to lack self-sustaining stability. .. If the container 3 falls on the first conveyor 40 or the second conveyor 42, the container inspection device 1 is urgently stopped, so that the processing capacity of the container inspection device 1 per unit time is significantly reduced. Therefore, it is important to stabilize the movement of the container 3 from the first discharge unit 30 (second discharge unit 32) to the first conveyor 40 (second conveyor 42).
　２．保持機構
　図２及び図３を用いて保持機構について説明する。本実施形態に係る容器検査装置１には、保持機構として第１保持機構５０及び第２保持機構５２を備えるが、基本的な構成は両機構とも同じであるため、主に第１保持機構５０について説明する。 2. 2. Holding Mechanism A holding mechanism will be described with reference to FIGS. 2 and 3. The container inspection device 1 according to the present embodiment includes a first holding mechanism 50 and a second holding mechanism 52 as holding mechanisms, but since the basic configuration is the same for both mechanisms, the first holding mechanism 50 is mainly provided. Will be described.
　図２に示すように、第１保持機構５０は、第１スターホイール１０及び第２スターホイール１２の回転によって第１排出部３０に搬送される容器３の側面に接触可能な少なくとも１本のアームと、アームを回転させて第１保持機構５０を閉状態と開状態とに切り替える電動モーター５７と、を備える。「閉状態」は、容器３の側面にアームが接触して、第１方向Ｄ１への容器３の移動をアームが制限する。開状態は、アームが回転して容器３の側面との接触を解除する。本実施形態の第１保持機構５０では上下及び左右に合計４本のアームを備える例について説明する。 As shown in FIG. 2, the first holding mechanism 50 has at least one arm that can come into contact with the side surface of the container 3 that is conveyed to the first discharge unit 30 by the rotation of the first star wheel 10 and the second star wheel 12. And an electric motor 57 that rotates the arm to switch the first holding mechanism 50 between the closed state and the open state. In the "closed state", the arm comes into contact with the side surface of the container 3, and the arm restricts the movement of the container 3 in the first direction D1. In the open state, the arm rotates to release the contact with the side surface of the container 3. An example in which the first holding mechanism 50 of the present embodiment includes a total of four arms in the vertical and horizontal directions will be described.
　図２に示すように、第１保持機構５０は、第１コンベヤ４０を挟んで容器３の全幅Ｗより広い第１間隔Ｗ１で立設する２本の回転軸である第１回転軸５３及び第２回転軸５４と、第１回転軸５３及び第２回転軸５４のそれぞれに上下に第２間隔Ｗ２をあけて配置される２本のアームである第１アーム５５及び第２アーム５６と、第１回転軸５３及び第２回転軸５４を回転駆動する電動モーター５７と、を備える。電動モーター５７により第１アーム５５及び第２アーム５６の開閉を高速化できる。上下に配置された第１アーム５５と第２アーム５６で容器３の側面の上下の２か所を保持できるので、揺れやすい容器形状であっても第１スターホイール１０及び第２スターホイール１２から第１コンベヤ４０上への移動時に容器３の自立安定性を向上できる。本実施形態ではアームを上下に２本配置したが、これに限らず、各回転軸に１本のアームとしてもよい。また、第１回転軸５３及び第２回転軸５４のそれぞれに固定された第１アーム５５及び第２アーム５６が観音開きのように開閉することで、第１排出部３０から第１コンベヤ４０上へ搬送される容器３の移動を速やかに行うことができる。その結果、上記容器検査装置１によれば、第１排出部３０におけるスターホイールの停止時間を短縮することができる。また、第１アーム５５及び第２アーム５６が第１方向Ｄ１に開くので容器３の移動を阻害することがなく、揺れやすい容器形状であっても高速排出時の容器３の自立安定性を向上できる。 As shown in FIG. 2, the first holding mechanism 50 is a first rotating shaft 53 and a first rotating shaft 53, which are two rotating shafts erected at a first interval W1 wider than the total width W of the container 3 with the first conveyor 40 interposed therebetween. The first arm 55 and the second arm 56, which are two arms arranged with a second interval W2 above and below each of the two rotation shafts 54, the first rotation shaft 53, and the second rotation shaft 54, and the second arm. It includes an electric motor 57 that rotationally drives the first rotating shaft 53 and the second rotating shaft 54. The electric motor 57 can speed up the opening and closing of the first arm 55 and the second arm 56. Since the first arm 55 and the second arm 56 arranged vertically can hold two places above and below the side surface of the container 3, even if the container shape is easily shaken, the first star wheel 10 and the second star wheel 12 can be used. The self-sustaining stability of the container 3 can be improved when moving onto the first conveyor 40. In the present embodiment, two arms are arranged vertically, but the present invention is not limited to this, and one arm may be used for each rotation axis. Further, the first arm 55 and the second arm 56 fixed to the first rotating shaft 53 and the second rotating shaft 54 are opened and closed like a double door, so that the first discharging unit 30 moves onto the first conveyor 40. The container 3 to be transported can be moved quickly. As a result, according to the container inspection device 1, the stop time of the star wheel in the first discharge unit 30 can be shortened. Further, since the first arm 55 and the second arm 56 open in the first direction D1, the movement of the container 3 is not hindered, and the self-sustaining stability of the container 3 at the time of high-speed discharge is improved even if the container shape is easily shaken. it can.
　第１方向Ｄ１は、容器３が第１押出機構６０で収容部１６から押し出される方向であり、第１コンベヤ４０の搬送方向と同じである。第１回転軸５３及び第２回転軸５４は、第１コンベヤ４０を挟んで立設する。第１回転軸５３及び第２回転軸５４は、下端がそれぞれ電動モーター５７に接続し、鉛直方向の上方に延びて容器３の首部の高さ付近でその上端が回転可能に支持される。 The first direction D1 is the direction in which the container 3 is pushed out from the accommodating portion 16 by the first extrusion mechanism 60, which is the same as the transport direction of the first conveyor 40. The first rotating shaft 53 and the second rotating shaft 54 are erected with the first conveyor 40 interposed therebetween. The lower ends of the first rotating shaft 53 and the second rotating shaft 54 are connected to the electric motor 57, respectively, and extend upward in the vertical direction, and the upper ends thereof are rotatably supported near the height of the neck of the container 3.
　電動モーター５７は、第１回転軸５３及び第２回転軸５４のそれぞれに設けられているが、１つの電動モーター５７の出力を第１回転軸５３及び第２回転軸５４の回転に分けて用いてもよい。電動モーター５７は、第１回転軸５３及び第２回転軸５４を軸周りに９０度の角度で往復回転することができる。電動モーター５７は、サーボモーターであることができる。サーボモーターを採用することで第１回転軸５３及び第２回転軸５４を高速で回転することができる。 The electric motor 57 is provided on each of the first rotating shaft 53 and the second rotating shaft 54, and the output of one electric motor 57 is used separately for the rotation of the first rotating shaft 53 and the second rotating shaft 54. You may. The electric motor 57 can reciprocate around the first rotating shaft 53 and the second rotating shaft 54 at an angle of 90 degrees. The electric motor 57 can be a servo motor. By adopting the servomotor, the first rotating shaft 53 and the second rotating shaft 54 can be rotated at high speed.
　電動モーター５７は、第１回転軸５３及び第２回転軸５４を回転して、第１アーム５５及び第２アーム５６を閉状態と開状態とに切り替え可能である。閉状態は、第１排出部３０にある容器３の側面に第１アーム５５及び第２アーム５６それぞれの接触部５５４が接触して容器３の第１方向Ｄ１への移動を制限する。開状態は、第１アーム５５及び第２アーム５６が第１コンベヤ４０側へ回動して第１排出部３０から第１方向Ｄ１への容器３の移動を許容する。第１アーム５５及び第２アーム５６は、第１回転軸５３と第２回転軸５４とを中心に旋回することで図２の正面視で観音開きに開閉する。 The electric motor 57 can rotate the first rotating shaft 53 and the second rotating shaft 54 to switch the first arm 55 and the second arm 56 between the closed state and the open state. In the closed state, the contact portions 554 of the first arm 55 and the second arm 56 each come into contact with the side surface of the container 3 in the first discharge portion 30, and the movement of the container 3 in the first direction D1 is restricted. In the open state, the first arm 55 and the second arm 56 rotate toward the first conveyor 40 to allow the container 3 to move from the first discharge unit 30 to the first direction D1. The first arm 55 and the second arm 56 open and close in a double door in the front view of FIG. 2 by turning around the first rotation shaft 53 and the second rotation shaft 54.
　第１アーム５５及び第２アーム５６は、それぞれ第１回転軸５３または第２回転軸５４に固定される固定端５５０と、固定端５５０とは反対側の自由端５５２と、自由端５５２に隣接する図３に示す接触部５５４と、を有する。一方の第１回転軸５３に固定された第１アーム５５及び第２アーム５６の自由端５５２と、他方の第２回転軸５４に固定された第１アーム５５及び第２アーム５６の自由端５５２とは、閉状態でそれぞれが固定された第１回転軸５３及び第２回転軸５４（固定端５５０）から互いに近づくように延在する。第１アーム５５及び第２アーム５６は、それぞれ合成樹脂製の屈曲した板状体である。第１アーム５５及び第２アーム５６の材質としては、加工しやすい合成樹脂製が望ましいが、容器３の側面を傷つけない材質であれば合成樹脂に限るものではない。なお、容器検査装置１において容器３の表面に接触する部材には第１アーム５５等と同様に傷をつけない材質が望ましく、また、それ以外の部材には機械に用いられる金属等の材質を用いることができる。 The first arm 55 and the second arm 56 are adjacent to a fixed end 550 fixed to the first rotating shaft 53 or the second rotating shaft 54, a free end 552 opposite to the fixed end 550, and a free end 552, respectively. It has a contact portion 554 shown in FIG. The free ends 552 of the first arm 55 and the second arm 56 fixed to one first rotating shaft 53, and the free ends 552 of the first arm 55 and the second arm 56 fixed to the other second rotating shaft 54. Means extending from the first rotating shaft 53 and the second rotating shaft 54 (fixed end 550), which are fixed in the closed state, so as to approach each other. The first arm 55 and the second arm 56 are bent plate-like bodies made of synthetic resin, respectively. The material of the first arm 55 and the second arm 56 is preferably made of a synthetic resin that is easy to process, but the material is not limited to the synthetic resin as long as it does not damage the side surface of the container 3. In the container inspection device 1, it is desirable that the member that comes into contact with the surface of the container 3 is made of a material that does not damage the first arm 55 or the like, and that the other members are made of a material such as metal used for a machine. Can be used.
　第１アーム５５は、第１排出部３０に停止した容器３の全高Ｈの１／２より高い位置である第１高さＨ１にある。第２アームは、容器３の全高Ｈの１／２より低い位置である第２高さＨ２にある。また、第１押出機構６０は、第１アーム５５の第１高さＨ１と第２アーム５６の第２高さＨ２との間の高さで容器３を第１コンベヤ４０側へ押すことができる。容器３の全高Ｈの上半分の位置にある第１アーム５５と同下半分の位置にある第２アーム５６により、容器３の自立安定性を確保しつつ、第１押出機構６０が第１アーム５５と第２アーム５６との間で容器３を押すことで容器３を確実に周縁１４より外の第１コンベヤ４０上へ移動させることができる。第１押出機構６０の押出板６５の高さは、容器３の重心の高さに設定されることが容器３の自立安定性を高めるために好ましい。また、各回転軸に１本のアームを設ける場合には、第１押出機構６０は当該アームと略同じ高さで容器３を押すことが望ましい。 The first arm 55 is at the first height H1 which is higher than 1/2 of the total height H of the container 3 stopped at the first discharge unit 30. The second arm is at a second height H2, which is lower than 1/2 of the total height H of the container 3. Further, the first extrusion mechanism 60 can push the container 3 toward the first conveyor 40 at a height between the first height H1 of the first arm 55 and the second height H2 of the second arm 56. .. The first arm 55 located in the upper half of the total height H of the container 3 and the second arm 56 located in the lower half of the container 3 ensure the self-sustaining stability of the container 3, and the first extrusion mechanism 60 is the first arm. By pushing the container 3 between the 55 and the second arm 56, the container 3 can be reliably moved onto the first conveyor 40 outside the peripheral edge 14. It is preferable that the height of the extrusion plate 65 of the first extrusion mechanism 60 is set to the height of the center of gravity of the container 3 in order to enhance the self-sustaining stability of the container 3. Further, when one arm is provided for each rotation shaft, it is desirable that the first extrusion mechanism 60 pushes the container 3 at substantially the same height as the arm.
　第１アーム５５及び第２アーム５６の自由端５５２は、閉状態で固定端５５０より第１排出部３０に停止した収容部１６側にある。言い換えれば、自由端５５２は、閉状態で第１回転軸５３及び第２回転軸５４を結ぶ仮想直線より第１排出部３０に停止した収容部１６側にある。自由端５５２が収容部１６に近い位置にあることで閉状態において収容部１６内に容器３をより確実に保持することができる。したがって、閉状態で固定端５５０は自由端５５２よりも収容部１６から離れた位置にある。固定端５５０が収容部１６から離れた位置にあることで、第１スターホイール１０の回転によって搬送される容器３と固定端５５０とが接触しない。 The free ends 552 of the first arm 55 and the second arm 56 are on the accommodating portion 16 side stopped at the first discharging portion 30 from the fixed end 550 in the closed state. In other words, the free end 552 is on the accommodating portion 16 side stopped at the first discharging portion 30 from the virtual straight line connecting the first rotating shaft 53 and the second rotating shaft 54 in the closed state. Since the free end 552 is located close to the accommodating portion 16, the container 3 can be more reliably held in the accommodating portion 16 in the closed state. Therefore, in the closed state, the fixed end 550 is located farther from the accommodating portion 16 than the free end 552. Since the fixed end 550 is located away from the accommodating portion 16, the container 3 conveyed by the rotation of the first star wheel 10 and the fixed end 550 do not come into contact with each other.
　第１間隔Ｗ１は、容器３の全幅Ｗに合わせて第１間隔調整機構５８により調整することができる。第１間隔調整機構５８は、ハンドル５８０と、２組のボールねじ機構５８２とを備える。ボールねじ機構５８２は、ねじ軸を共通とし、ハンドル５８０を回してねじ軸を回転することでナットに固定された２つの電動モーター５７が互いに近接移動または離間移動する。したがって、第１間隔調整機構５８によれば、電動モーター５７に固定された第１回転軸５３及び第２回転軸５４の第１間隔Ｗ１を変更することができる。 The first interval W1 can be adjusted by the first interval adjusting mechanism 58 according to the total width W of the container 3. The first interval adjusting mechanism 58 includes a handle 580 and two sets of ball screw mechanisms 582. In the ball screw mechanism 582, the screw shaft is common, and the two electric motors 57 fixed to the nut move close to each other or separate from each other by turning the handle 580 to rotate the screw shaft. Therefore, according to the first interval adjusting mechanism 58, the first interval W1 of the first rotating shaft 53 and the second rotating shaft 54 fixed to the electric motor 57 can be changed.
　第２間隔Ｗ２は、容器３の全高Ｈや容器３の上下の重量配分に合わせて変更することができる。第１回転軸５３及び第２回転軸５４には鉛直方向に延びる長孔５９が形成される。長孔５９には固定端５５０が取付ボルトで固定される。固定端５５０の取付ボルトを緩めて、取付ボルトを長孔５９に沿って移動させることで、第１アーム５５及び第２アーム５６を長孔５９に沿って移動することができる。例えば、容器３の全高Ｈが高くなれば第１アーム５５及び第２アーム５６を上方へ移動し、容器３の全高Ｈが低くなれば第１アーム５５及び第２アーム５６を下方へ移動する。 The second interval W2 can be changed according to the total height H of the container 3 and the weight distribution above and below the container 3. An elongated hole 59 extending in the vertical direction is formed in the first rotating shaft 53 and the second rotating shaft 54. A fixing end 550 is fixed to the elongated hole 59 with a mounting bolt. By loosening the mounting bolt of the fixed end 550 and moving the mounting bolt along the elongated hole 59, the first arm 55 and the second arm 56 can be moved along the elongated hole 59. For example, when the total height H of the container 3 is high, the first arm 55 and the second arm 56 are moved upward, and when the total height H of the container 3 is low, the first arm 55 and the second arm 56 are moved downward.
　また、図１及び図３に示す第２排出部３２における第２保持機構５２は、第１保持機構５０と基本的に同じ構成であり、閉状態と開状態とに切り替わる。開状態においては、第２排出部３２にある容器３に対して第２押出機構６２を作用させることにより、容器３を第２方向Ｄ２に押して第２コンベヤ４２上へ移動する。第２保持機構５２の第１回転軸５３、第２回転軸５４、第１アーム５５、第２アーム５６、及び電動モーター５７は、第１保持機構５０の各部材と同じ構成及び機能を有するため、重複する説明は省略する。 Further, the second holding mechanism 52 in the second discharging unit 32 shown in FIGS. 1 and 3 has basically the same configuration as the first holding mechanism 50, and switches between a closed state and an open state. In the open state, the second extrusion mechanism 62 acts on the container 3 in the second discharge unit 32 to push the container 3 in the second direction D2 and move it onto the second conveyor 42. Since the first rotating shaft 53, the second rotating shaft 54, the first arm 55, the second arm 56, and the electric motor 57 of the second holding mechanism 52 have the same configurations and functions as the respective members of the first holding mechanism 50. , Duplicate description is omitted.
　３．押出機構
　図１～図３を用いて押出機構について説明する。本実施形態に係る容器検査装置１には、押出機構として第１押出機構６０及び第２押出機構６２を備えるが、基本的な構成は同じであるため、主に第１押出機構６０について説明する。 3. 3. Extrusion mechanism The extrusion mechanism will be described with reference to FIGS. 1 to 3. The container inspection device 1 according to the present embodiment includes a first extrusion mechanism 60 and a second extrusion mechanism 62 as extrusion mechanisms, but since the basic configurations are the same, the first extrusion mechanism 60 will be mainly described. ..
　図１～図３に示すように、第１押出機構６０は、機台２上に立設する支持部６４と、支持部６４に支持される押出板６５と、を備える。押出板６５は、第１排出部３０に停止する容器３に対して進退移動する。第２押出機構６２は、支持部６４に支持される押出板６５を備える。押出板６５は、第２排出部３２に停止する容器３に対して進退移動する。押出板６５が支持部６４に支持されることで押出板６５の進退移動が安定し、容器３の自立安定性を向上できる。 As shown in FIGS. 1 to 3, the first extrusion mechanism 60 includes a support portion 64 erected on the machine base 2 and an extrusion plate 65 supported by the support portion 64. The extrusion plate 65 moves back and forth with respect to the container 3 stopped at the first discharge unit 30. The second extrusion mechanism 62 includes an extrusion plate 65 supported by the support portion 64. The extrusion plate 65 moves back and forth with respect to the container 3 that stops at the second discharge unit 32. Since the extruded plate 65 is supported by the support portion 64, the advancing / retreating movement of the extruded plate 65 is stable, and the self-sustaining stability of the container 3 can be improved.
　第１押出機構６０の押出板６５は、第１排出部３０の容器３に接触する。第１押出機構６０の押出板６５は、第１方向Ｄ１に常時付勢される。第１押出機構６０は、第１保持機構５０が閉状態で第１排出部３０に搬送された容器３に接触して押出板６５が後退し、第１保持機構５０が開状態となることにより、第１方向Ｄ１に押出板６５が前進して容器３を収容部１６から押し出す。押出板６５が容器３を排出方向（第１方向Ｄ１及び第２方向Ｄ２）に常時付勢することにより、容器３を迅速に排出することができる。 The extrusion plate 65 of the first extrusion mechanism 60 comes into contact with the container 3 of the first discharge unit 30. The extrusion plate 65 of the first extrusion mechanism 60 is constantly urged in the first direction D1. In the first extrusion mechanism 60, the extrusion plate 65 retracts in contact with the container 3 conveyed to the first discharge unit 30 with the first holding mechanism 50 closed, and the first holding mechanism 50 is opened. , The extrusion plate 65 advances in the first direction D1 and pushes the container 3 out of the accommodating portion 16. The extruded plate 65 constantly urges the container 3 in the discharge direction (first direction D1 and second direction D2), so that the container 3 can be quickly discharged.
　図１に示すように、第１スターホイール１０には、回転中心５を含む上下に貫通する第１貫通孔１１が形成される。図３に示すように、第２スターホイール１２には、回転中心５を含む上下に貫通する第２貫通孔１３が形成される。支持部６４は、第１貫通孔１１と第２貫通孔１３を貫通して機台２上に立設する円柱状のロッドである。支持部６４の下端は機台２に固定される。第１スターホイール１０及び第２スターホイール１２は、支持部６４の周囲を回転し、支持部６４は回転しない。 As shown in FIG. 1, the first star wheel 10 is formed with a first through hole 11 that penetrates vertically including the rotation center 5. As shown in FIG. 3, the second star wheel 12 is formed with a second through hole 13 that penetrates vertically including the rotation center 5. The support portion 64 is a columnar rod that penetrates the first through hole 11 and the second through hole 13 and stands on the machine base 2. The lower end of the support portion 64 is fixed to the machine base 2. The first star wheel 10 and the second star wheel 12 rotate around the support portion 64, and the support portion 64 does not rotate.
　支持部６４には水平方向に延びる取付板６９ａが固定される。取付板６９ａは支持部６４に沿って鉛直方向に移動可能であり、取付板６９ａの高さを変更することで押出板６５の高さを調整する。取付板６９ａには２枚のスライド板６９ｂが固定される。スライド板６９ｂは、ノブ６９ｃを回して固定ボルトを緩めることでスライド板６９ｂに設けられる長孔に沿って取付板６９ａの上を前後に移動可能である。スライド板６９ｂを前後に移動することで、収容部１６に押出板６５をどの程度突出した位置にするかを調整できる。押出板６５は、スライド板６９ｂの先端部から収容部１６（容器３）側に交差して延びる２本の押出アーム６８ａ、６８ｂを介して収容部１６に突出するように配置される。 A mounting plate 69a extending in the horizontal direction is fixed to the support portion 64. The mounting plate 69a can be moved in the vertical direction along the support portion 64, and the height of the extruded plate 65 is adjusted by changing the height of the mounting plate 69a. Two slide plates 69b are fixed to the mounting plate 69a. The slide plate 69b can be moved back and forth on the mounting plate 69a along the elongated holes provided in the slide plate 69b by turning the knob 69c to loosen the fixing bolt. By moving the slide plate 69b back and forth, it is possible to adjust how much the extrusion plate 65 protrudes from the accommodating portion 16. The extruded plate 65 is arranged so as to project from the tip end portion of the slide plate 69b to the accommodating portion 16 via two extrusion arms 68a and 68b extending so as to intersect the accommodating portion 16 (container 3) side.
　押出板６５は、収容部１６内に突出する方向に常時付勢される。押出アーム６８ａ及び押出アーム６８ｂは、スライド板６９ｂに付勢部材６６ａ及び付勢部材６６ｂを介して取り付けられる。付勢部材６６ａは押出アーム６８ａをスライド板６９ｂに対して図３における右回転する方向に付勢し、付勢部材６６ｂは押出アーム６８ｂをスライド板６９ｂに対して図３における左回転する方向に付勢する。したがって、押出アーム６８ａと押出アーム６８ｂの先端は互いに近づく方向に常時付勢される。押出アーム６８ａの先端は押出板６５に回転自在に固定される。押出板６５には長孔６５ａが開口し、長孔６５ａは押出アーム６８ｂの先端に設けられたカムフォロア６７を受け入れ、カムフォロア６７は長孔６５ａに沿って移動可能である。 The extruded plate 65 is constantly urged in the direction of projecting into the accommodating portion 16. The extrusion arm 68a and the extrusion arm 68b are attached to the slide plate 69b via the urging member 66a and the urging member 66b. The urging member 66a urges the extrusion arm 68a with respect to the slide plate 69b in the clockwise direction in FIG. 3, and the urging member 66b urges the extrusion arm 68b with respect to the slide plate 69b in the counterclockwise rotation direction in FIG. Encourage. Therefore, the tips of the extrusion arm 68a and the extrusion arm 68b are constantly urged in the direction of approaching each other. The tip of the extrusion arm 68a is rotatably fixed to the extrusion plate 65. An elongated hole 65a is opened in the extrusion plate 65, the elongated hole 65a receives a cam follower 67 provided at the tip of the extrusion arm 68b, and the cam follower 67 can move along the elongated hole 65a.
　収容部１６に容器３が収容されていない状態では、図３の第２排出部３２で示すように、押出アーム６８ａの先端にカムフォロア６７が近づくように移動して、押出板６５の先端が収容部１６内に押し出される。 When the container 3 is not accommodated in the accommodating portion 16, as shown by the second discharge portion 32 in FIG. 3, the cam follower 67 moves so as to approach the tip of the extrusion arm 68a, and the tip of the extrusion plate 65 is accommodated. It is extruded into the part 16.
　押出板６５は、押出板６５に対して第２スターホイール１２によって容器３が搬送されてくる側に面取り部６５ｂを有する。面取り部６５ｂは、搬送されてきた容器３の胴部に接触して押出板６５をスライド板６９ｂ側に押し戻す機能を有する。押し戻された押出板６５は、付勢部材６６ａ，６６ｂによって容器３を第１方向Ｄ１に押し出すように常時付勢する。また、容器３は第１方向Ｄ１に向かって常時駆動している第１コンベヤ４０上にあり、容器３の底部が第１コンベヤ４０に摺接している。 The extruded plate 65 has a chamfered portion 65b on the side where the container 3 is conveyed by the second star wheel 12 with respect to the extruded plate 65. The chamfered portion 65b has a function of contacting the body portion of the conveyed container 3 and pushing the extruded plate 65 back toward the slide plate 69b. The extruded plate 65 pushed back is constantly urged by the urging members 66a and 66b so as to push the container 3 in the first direction D1. Further, the container 3 is on the first conveyor 40 which is constantly driven toward the first direction D1, and the bottom of the container 3 is in sliding contact with the first conveyor 40.
　図３における第１排出部３０では第１保持機構５０の第１アーム５５（及び第２アーム５６）が閉状態にあり、第１アーム５５の接触部５５４が容器３に接触して、押出板６５の押出力に抗して容器３を収容部１６内に保持する。 In the first discharge unit 30 in FIG. 3, the first arm 55 (and the second arm 56) of the first holding mechanism 50 is in a closed state, and the contact portion 554 of the first arm 55 comes into contact with the container 3 to make an extrusion plate. The container 3 is held in the accommodating portion 16 against the extrusion force of 65.
　第１アーム５５が図３に破線で示す位置に移動して開状態になると、容器３は、押出板６５によって第１方向Ｄ１に押し出され、かつ、第１コンベヤ４０に乗って第１方向Ｄ１に移動する。第１アーム５５の下に配置された図２に示す第２アーム５６も第１アーム５５と同様に動作するため、容器３の自立状態をより安定的に維持したまま容器３が第１コンベヤ４０に乗って移動できる。 When the first arm 55 moves to the position shown by the broken line in FIG. 3 and is opened, the container 3 is extruded in the first direction D1 by the extrusion plate 65 and rides on the first conveyor 40 in the first direction D1. Move to. Since the second arm 56 shown in FIG. 2 arranged below the first arm 55 also operates in the same manner as the first arm 55, the container 3 is placed on the first conveyor 40 while maintaining the self-supporting state of the container 3 more stably. You can move on a conveyor belt.
　４．変形例
　変形例に係る容器検査装置１ａについて説明する。図４は変形例に係る容器検査装置１ａの平面図の部分拡大図であり、図５は変形例に係る容器検査装置１ａの側面図であり、図６は変形例に係る容器検査装置１ａの第１排出部３０の背面図である。ここでは、上記実施形態に係る容器検査装置１と同一の構成については同一の符号を用い、重複する説明を省略する。また、第２排出部３２は、第１排出部３０と同様の構成であるため、ここでは第１排出部３０についてのみ説明する。図６は第１方向Ｄ１に沿って収容部側から容器３を見ているため、第１押出機構６００等を省略して示す。 4. Modified Example The container inspection device 1a according to the modified example will be described. FIG. 4 is a partially enlarged view of a plan view of the container inspection device 1a according to the modified example, FIG. 5 is a side view of the container inspection device 1a according to the modified example, and FIG. 6 is a side view of the container inspection device 1a according to the modified example. It is a rear view of the 1st discharge part 30. Here, the same reference numerals are used for the same configuration as the container inspection device 1 according to the above embodiment, and duplicate description will be omitted. Further, since the second discharge unit 32 has the same configuration as the first discharge unit 30, only the first discharge unit 30 will be described here. In FIG. 6, since the container 3 is viewed from the accommodating portion side along the first direction D1, the first extrusion mechanism 600 and the like are omitted.
　４．１．保持機構
　図４～図６に示すように、変形例に係る容器検査装置１ａは、第１排出部３０に臨んで機台２に支持される第１保持機構５００を有する。 4.1. Holding Mechanism As shown in FIGS. 4 to 6, the container inspection device 1a according to the modified example has a first holding mechanism 500 that faces the first discharge unit 30 and is supported by the machine base 2.
　第１保持機構５００は、１本のアーム５６０と、アーム５６０を揺動する電動モーター５７０と、を備える。電動モーター５７０は、例えばサーボモーターである。電動モーター５７０は、機台２に固定される。 The first holding mechanism 500 includes one arm 560 and an electric motor 570 that swings the arm 560. The electric motor 570 is, for example, a servo motor. The electric motor 570 is fixed to the machine base 2.
　アーム５６０は、電動モーター５７０の回転軸５３０に固定された固定端５６１と、固定端５６１と反対側の自由端５６２と、を有する。固定端５６１と自由端５６２との間には、第１排出部３０に停止する容器３の側面に接触する接触部５６４を有する。自由端５６２は、閉状態で固定端５６１より第１排出部３０に停止した収容部１６側にある。 The arm 560 has a fixed end 561 fixed to the rotating shaft 530 of the electric motor 570 and a free end 562 opposite to the fixed end 561. Between the fixed end 561 and the free end 562, there is a contact portion 564 that contacts the side surface of the container 3 that stops at the first discharge portion 30. The free end 562 is on the accommodating portion 16 side stopped at the first discharging portion 30 from the fixed end 561 in the closed state.
　電動モーター５７０の回転軸５３０は、図４の平面視で第１方向Ｄ１と平行であり、図５の側面視で第１排出部３０に向かって上方に傾いている。上方への傾きは、例えば水平面に対して１０度～２０度程度である。電動モーター５７０を駆動すると、回転軸５３０が回転し、固定端５６１を中心に自由端５６２が弧を描くように移動して、アーム５６０が揺動する。図６に示すように、閉状態でアーム５６０は水平であり、開状態でアーム５６０は背面視で垂直であるので、揺動角は９０度である。揺動角は、閉状態で容器３を確実に保持可能であり、かつ、開状態で排出される容器３と干渉しない範囲で変更可能である。 The rotation shaft 530 of the electric motor 570 is parallel to the first direction D1 in the plan view of FIG. 4, and is inclined upward toward the first discharge portion 30 in the side view of FIG. The upward inclination is, for example, about 10 to 20 degrees with respect to the horizontal plane. When the electric motor 570 is driven, the rotating shaft 530 rotates, the free end 562 moves in an arc around the fixed end 561, and the arm 560 swings. As shown in FIG. 6, since the arm 560 is horizontal in the closed state and the arm 560 is vertical in the rear view in the open state, the swing angle is 90 degrees. The swing angle can be changed within a range in which the container 3 can be reliably held in the closed state and does not interfere with the container 3 discharged in the open state.
　図４～図６において破線の矢印でアーム５６０の開動作を示す。電動モーター５７０を駆動して、回転軸５３０を中心にアーム５６０を上方へ揺動することにより、自由端５６２が第１排出部３０から離れる方向へ移動しながら上方へ移動する。これにより、第１保持機構５００が閉状態から開状態となる。第１保持機構５００は、構成が簡単でありながらアーム５６０の開閉を高速化できる。また、このように少なくとも回転軸５３０を上方へ傾けることにより、自由端５６２を、単に上方へ移動させるのではなく、第１排出部３０から離れる方向へ移動しながら開動作することで、容器３に対し上方へ持ち上げる力を低減することができ、容器３の自立安定性を向上できる。 In FIGS. 4 to 6, the broken line arrow indicates the opening operation of the arm 560. By driving the electric motor 570 and swinging the arm 560 upward about the rotation shaft 530, the free end 562 moves upward while moving in a direction away from the first discharge portion 30. As a result, the first holding mechanism 500 changes from the closed state to the open state. The first holding mechanism 500 can speed up the opening and closing of the arm 560 while being simple in configuration. Further, by tilting at least the rotation shaft 530 upward in this way, the free end 562 is not simply moved upward, but is opened while moving away from the first discharge portion 30 to open the container 3. It is possible to reduce the force of lifting upwards and improve the self-sustaining stability of the container 3.
　４．２．押出機構
　図４及び図５に示すように、第１押出機構６００は、支持部６４に水平に固定された取付板６９０と、長孔６９１に沿って取付板６９０上を前後に移動可能なスライド板６９２と、スライド板６９２から収容部１６（容器３）側に延びる押出板６５０と、を備える。 4.2. Extrusion mechanism As shown in FIGS. 4 and 5, the first extrusion mechanism 600 has a mounting plate 690 fixed horizontally to the support portion 64 and a slide that can move back and forth on the mounting plate 690 along the elongated hole 691. A plate 692 and an extruded plate 650 extending from the slide plate 692 toward the accommodating portion 16 (container 3) are provided.
　スライド板６９２は、第１方向Ｄ１に直交する方向に延びるレール６９３と、第１方向Ｄ１に沿って延びるガイド６９４と、を備える。レール６９３は、凹溝に形成される。ガイド６９４は、スライド板６９２の上面から突出し、第１方向Ｄ１に沿って延びる板状である。 The slide plate 692 includes a rail 693 extending in a direction orthogonal to the first direction D1 and a guide 694 extending along the first direction D1. The rail 693 is formed in a concave groove. The guide 694 has a plate shape that protrudes from the upper surface of the slide plate 692 and extends along the first direction D1.
　押出板６５０は、第１方向Ｄ１に沿って延びる板状であり、先端に接触板６５１と、後端に摺動溝６５３と、上面に付勢部材６６０と、を備える。 The extruded plate 650 has a plate shape extending along the first direction D1, and includes a contact plate 651 at the tip, a sliding groove 653 at the rear end, and an urging member 660 on the upper surface.
　接触板６５１は、容器に接触しても傷がつかない材質、例えば合成樹脂製であり、容器３の搬入側に面取り部６５２を有する。 The contact plate 651 is made of a material that will not be scratched even if it comes into contact with the container, for example, a synthetic resin, and has a chamfered portion 652 on the carry-in side of the container 3.
　摺動溝６５３は、押出板６５０の後端に開口する切り欠き溝であり、第１方向Ｄ１に沿って延びて形成される。摺動溝６５３内にガイド６９４が挿入され、ガイド６９４の側面に摺動溝６５３が摺接することで第１方向Ｄ１に沿って押出板６５０が進退移動する。押出板６５０は、スライド板６９２の上面と、ガイド６９４の上に固定された押さえ板６９５との間に挟持される。よって、押出板６５０は、上下をスライド板６９２と押さえ板６９５によって案内され、第１方向Ｄ１に直交する方向をガイド６９４によって案内されて進退移動可能である。 The sliding groove 653 is a notch groove that opens at the rear end of the extrusion plate 650, and is formed so as to extend along the first direction D1. The guide 694 is inserted into the sliding groove 653, and the sliding groove 653 is in sliding contact with the side surface of the guide 694, so that the extrusion plate 650 moves back and forth along the first direction D1. The extruded plate 650 is sandwiched between the upper surface of the slide plate 692 and the holding plate 695 fixed on the guide 694. Therefore, the extrusion plate 650 can move forward and backward by being guided up and down by the slide plate 692 and the pressing plate 695 and guided by the guide 694 in the direction orthogonal to the first direction D1.
　付勢部材６６０は、スライド板６９２に対して図３における左回転する方向に付勢された押出アーム６８０と、押出アーム６８０の先端に取り付けられたカムフォロア６７０と、を備える。カムフォロア６７０は、レール６９３に沿って第１方向Ｄ１に直交する方向に転がり移動可能である。したがって、付勢部材６６０は、押出アーム６８０をカムフォロア６７０が図４の上方へ向かって移動するように常時付勢し、その結果、付勢部材６６０が固定された押出板６５０をスライド板６９２に対して第１方向Ｄ１に押し出すように常時付勢する。 The urging member 660 includes an extrusion arm 680 urged in the counterclockwise direction in FIG. 3 with respect to the slide plate 692, and a cam follower 670 attached to the tip of the extrusion arm 680. The cam follower 670 can roll and move along the rail 693 in a direction orthogonal to the first direction D1. Therefore, the urging member 660 constantly urges the extrusion arm 680 so that the cam follower 670 moves upward in FIG. 4, and as a result, the extrusion plate 650 to which the urging member 660 is fixed is attached to the slide plate 692. On the other hand, it is always urged to push it in the first direction D1.
　収容部１６に容器３が収容されていない状態では、押出板６５０の接触板６５１が収容部１６内まで押し出される。第１スターホイール１０及び第２スターホイール１２が回転して、第１排出部３０に容器３が搬入されると、容器３の側面に面取り部６５２が最初に接触する。容器３が第１排出部３０に近づくにつれて、容器３が面取り部６５２を摺動しながら押出板６５０を後退させる。このとき、カムフォロア６７０はレール６９３内を転動し、摺動溝６５３はガイド６９４に案内されて図４に示す状態となる。 When the container 3 is not accommodated in the accommodating portion 16, the contact plate 651 of the extruded plate 650 is pushed out into the accommodating portion 16. When the first star wheel 10 and the second star wheel 12 rotate and the container 3 is carried into the first discharge portion 30, the chamfered portion 652 first comes into contact with the side surface of the container 3. As the container 3 approaches the first discharge portion 30, the container 3 retracts the extrusion plate 650 while sliding the chamfered portion 652. At this time, the cam follower 670 rolls in the rail 693, and the sliding groove 653 is guided by the guide 694 to the state shown in FIG.
　電動モーター５７０を駆動して第１保持機構５００が閉状態から開状態へ移ると、付勢部材６６０は押出アーム６８０を左回転させてカムフォロア６７０がレール６９３内を図４の上方へ転動する。これにより、押出板６５０は、ガイド６９４に沿って第１方向Ｄ１に押し出され、接触板６５１が容器３の側面を押すことで第１コンベヤ４０上へ容器３を迅速に排出する。 When the electric motor 570 is driven to move the first holding mechanism 500 from the closed state to the open state, the urging member 660 rotates the extrusion arm 680 counterclockwise, and the cam follower 670 rolls in the rail 693 upward in FIG. .. As a result, the extruded plate 650 is extruded in the first direction D1 along the guide 694, and the contact plate 651 pushes the side surface of the container 3 to quickly discharge the container 3 onto the first conveyor 40.
　５．昇降部
　図１及び図７～図９を用いて昇降部１００について説明する。図７は本実施形態に係る撮像部２８が検査位置にある容器検査装置１の正面図であり、図８は本実施形態に係る撮像部２８がメンテナンス位置にある容器検査装置１の正面図であり、図９は昇降部１００の平面図である。図７及び図８では第１スターホイール１０及び第２スターホイール１２等の機台２の上にある機構を省略して示す。 5. Elevating part The elevating part 100 will be described with reference to FIGS. 1 and 7 to 9. FIG. 7 is a front view of the container inspection device 1 in which the imaging unit 28 according to the present embodiment is in the inspection position, and FIG. 8 is a front view of the container inspection device 1 in which the imaging unit 28 according to the present embodiment is in the maintenance position. Yes, FIG. 9 is a plan view of the elevating part 100. In FIGS. 7 and 8, the mechanisms on the machine base 2 such as the first star wheel 10 and the second star wheel 12 are omitted.
　図１に示すように、検査部２０は、第１スターホイール１０の周縁１４に沿って配置される。フレーム１１０は、機台２の周囲を囲むように配置される。フレーム１１０は、角型鋼管を溶接して枠体に形成される。フレーム１１０は、機台２から離間して配置される。 As shown in FIG. 1, the inspection unit 20 is arranged along the peripheral edge 14 of the first star wheel 10. The frame 110 is arranged so as to surround the periphery of the machine base 2. The frame 110 is formed into a frame by welding a square steel pipe. The frame 110 is arranged apart from the machine base 2.
　図７に示すように、フレーム１１０は、機台２と同じ設置面上に設置され、容器３が搬送される高さより高い位置まで上方に延びる。フレーム１１０の上端には昇降部１００が設けられる。 As shown in FIG. 7, the frame 110 is installed on the same installation surface as the machine base 2, and extends upward to a position higher than the height at which the container 3 is conveyed. An elevating portion 100 is provided at the upper end of the frame 110.
　検査部２０は、フレーム１１０から垂下され、かつ、容器３に対して光を出射する発光部２７と、フレーム１１０から垂下され、かつ、発光部２７の光が照射された容器３を撮像する撮像部２８と、を含む。撮像部２８は、容器３を挟んで発光部２７と対向して配置される。撮像部２８が容器３からの反射光で撮像する場合には発光部２７側に撮像部２８が設けられてもよい。 The inspection unit 20 takes an image of the light emitting unit 27 hanging from the frame 110 and emitting light to the container 3 and the container 3 hanging from the frame 110 and irradiated with the light of the light emitting unit 27. Part 28 and. The imaging unit 28 is arranged so as to face the light emitting unit 27 with the container 3 interposed therebetween. When the image pickup unit 28 takes an image with the reflected light from the container 3, the image pickup unit 28 may be provided on the light emitting unit 27 side.
　発光部２７及び撮像部２８は、フレーム１１０に固定される。発光部２７は、フレーム１１０から垂下され、かつ、容器３に対して光を出射する。撮像部２８は、フレーム１１０から垂下され、かつ、発光部２７の光が照射された容器３を撮像する。 The light emitting unit 27 and the imaging unit 28 are fixed to the frame 110. The light emitting unit 27 hangs down from the frame 110 and emits light to the container 3. The imaging unit 28 images the container 3 that hangs down from the frame 110 and is irradiated with the light of the light emitting unit 27.
　このように、第１スターホイール１０及び第２スターホイール１２の回転等により振動が発生する機台２からフレーム１１０が離間しているので、撮像部２８の振動が抑制され、撮像部２８で精度の高い画像を撮像できる。 In this way, since the frame 110 is separated from the machine base 2 where vibration is generated due to the rotation of the first star wheel 10 and the second star wheel 12, the vibration of the image pickup unit 28 is suppressed, and the accuracy of the image pickup unit 28 is suppressed. Can capture high-quality images.
　図７～図９に示すように、容器検査装置１は、容器３の搬送路の上方に昇降部１００を有する。昇降部１００は、発光部２７及び撮像部２８を容器３に対して昇降する。昇降部１００は、フレーム１１０の上に、昇降モーター１２０と、ボールねじ機構１２４と、昇降モーター１２０の駆動力をボールねじ機構１２４に伝達するベルト１２１及びギヤボックス１２２と、ボールねじ機構１２４のねじ軸１２５と平行にフレーム１１０から垂下された３本のガイド１２６と、を備える。昇降モーター１２０は、電動モーターである。 As shown in FIGS. 7 to 9, the container inspection device 1 has an elevating portion 100 above the transport path of the container 3. The elevating unit 100 elevates and elevates the light emitting unit 27 and the imaging unit 28 with respect to the container 3. On the frame 110, the elevating part 100 includes an elevating motor 120, a ball screw mechanism 124, a belt 121 and a gear box 122 that transmit the driving force of the elevating motor 120 to the ball screw mechanism 124, and a screw of the ball screw mechanism 124. It includes three guides 126 hanging from the frame 110 in parallel with the shaft 125. The elevating motor 120 is an electric motor.
　昇降部１００は、第１スターホイール１０及び第２スターホイール１２によって搬送される容器３の高さに合わせた図７に示す検査位置と、検査位置よりも上方の図８に示すメンテナンス位置とに発光部２７及び撮像部２８を昇降可能である。発光部２７及び撮像部２８は一体化されており、昇降モーター１２０の駆動によりねじ軸１２５を回転させると発光部２７及び撮像部２８はガイド１２６に案内されて昇降する。図７に示す検査位置に発光部２７及び撮像部２８がある状態でメンテナンスを行うと、第１スターホイール１０及び第２スターホイール１２や支持部６４に固定された第１押出機構６０及び第２押出機構６２のメンテナンス作業がやりにくい。これに対して、図８に示すメンテナンス位置に発光部２７及び撮像部２８があると、装置内部の作業性が格段に向上する。 The elevating part 100 has an inspection position shown in FIG. 7 according to the height of the container 3 conveyed by the first star wheel 10 and the second star wheel 12, and a maintenance position shown in FIG. 8 above the inspection position. The light emitting unit 27 and the imaging unit 28 can be raised and lowered. The light emitting unit 27 and the imaging unit 28 are integrated, and when the screw shaft 125 is rotated by driving the elevating motor 120, the light emitting unit 27 and the imaging unit 28 are guided by the guide 126 to move up and down. When maintenance is performed with the light emitting unit 27 and the imaging unit 28 at the inspection positions shown in FIG. 7, the first extrusion mechanism 60 and the second extrusion mechanism 60 fixed to the first star wheel 10, the second star wheel 12, and the support unit 64 are performed. Maintenance work of the extrusion mechanism 62 is difficult. On the other hand, if the light emitting unit 27 and the imaging unit 28 are located at the maintenance positions shown in FIG. 8, the workability inside the apparatus is remarkably improved.
　従来であれば、メンテナンス作業のたびに発光部２７と撮像部２８を容器検査装置１から取り外すことも多かったが、メンテナンス位置に発光部２７及び撮像部２８を上昇させてしまえばこれらを取り外さなくて済む。そのため、メンテナンス後に発光部２７と撮像部２８を再び検査位置に戻すための作業時間を短縮できる。また、昇降部１００により発光部２７等を上昇させることで、容器検査装置１内に、作業者がアクセスしやすくなり、かつ、作業者が部品等を出し入れしやすくなる。このようにメンテナンスに要する時間を短縮することにより、生産ラインを停止する時間も短縮できるため、結果的に容器３の生産性を向上できる。メンテナンスとしては、例えば第１押出機構６０等の各動作部の調整の他、容器３のデザインが変更された際の型替え作業等がある。型替え作業は、容器３のハンドリングに関わる部品の交換作業になるため、特に作業に時間を要する。型替え作業では、昇降部１００により発光部２７等を上昇させた状態で、例えば、支持部６４を機台２から取り外した後、第１スターホイール１０及び第２スターホイール１２をまとめて取り外し、変更後の容器３のデザインに合わせた新たな第１スターホイール１０及び第２スターホイール１２のセットを取り付ける。この取り付け後、再び昇降部１００により発光部２７等を検査位置に戻せば型替え作業が完了する。なお、昇降部１００を採用することにより、従来の昇降部１００が無かった装置に比べて、型替え作業に要する時間が半分以下に短縮できることも発明者等の実験により確認された。 In the past, the light emitting unit 27 and the imaging unit 28 were often removed from the container inspection device 1 every time maintenance work was performed, but once the light emitting unit 27 and the imaging unit 28 are raised to the maintenance position, they cannot be removed. It's done. Therefore, the work time for returning the light emitting unit 27 and the imaging unit 28 to the inspection position again after maintenance can be shortened. Further, by raising the light emitting unit 27 and the like by the elevating unit 100, it becomes easy for the operator to access the container inspection device 1, and it becomes easy for the operator to put in and take out parts and the like. By shortening the time required for maintenance in this way, the time for stopping the production line can also be shortened, and as a result, the productivity of the container 3 can be improved. Maintenance includes, for example, adjustment of each operating portion of the first extrusion mechanism 60 and the like, as well as mold change work when the design of the container 3 is changed. Since the mold change work is a replacement work of parts related to the handling of the container 3, the work is particularly time-consuming. In the mold change work, in a state where the light emitting portion 27 and the like are raised by the elevating portion 100, for example, after removing the support portion 64 from the machine base 2, the first star wheel 10 and the second star wheel 12 are removed together. A new set of the first star wheel 10 and the second star wheel 12 according to the changed design of the container 3 is attached. After this attachment, the light emitting portion 27 and the like are returned to the inspection position by the elevating portion 100 again to complete the mold change work. It was also confirmed by experiments by the inventors that the time required for the mold change work can be reduced to less than half by adopting the elevating part 100 as compared with the conventional device without the elevating part 100.
　昇降部１００は、昇降用ハンドル１３０をさらに備えてもよい。昇降用ハンドル１３０は、フレーム１１０から垂下され、容器３の上方に配置される。昇降用ハンドル１３０は、ベルト１２１にプーリーを介して連結される。昇降用ハンドル１３０を回すことで、ベルト１２１及びギヤボックス１２２を介してボールねじ機構１２４を駆動して発光部２７及び撮像部２８を昇降できる。昇降用ハンドル１３０を有することで、昇降モーター１２０が故障した場合や昇降モーター１２０に電力が供給されていない場合でも、発光部２７及び撮像部２８を昇降できる。 The elevating part 100 may further include an elevating handle 130. The elevating handle 130 hangs down from the frame 110 and is arranged above the container 3. The elevating handle 130 is connected to the belt 121 via a pulley. By turning the elevating handle 130, the ball screw mechanism 124 can be driven via the belt 121 and the gear box 122 to elevate the light emitting unit 27 and the imaging unit 28. By having the elevating handle 130, the light emitting unit 27 and the imaging unit 28 can be elevated even when the elevating motor 120 fails or power is not supplied to the elevating motor 120.
　昇降部１００は、ボールねじ機構１２４に限らず、ボールねじ機構１２４の代わりに発光部２７及び撮像部２８を昇降させる公知の直動機構を採用してもよい。 The elevating unit 100 is not limited to the ball screw mechanism 124, and a known linear motion mechanism that elevates and elevates the light emitting unit 27 and the imaging unit 28 may be adopted instead of the ball screw mechanism 124.
