Description

本発明は、容器を搬送する搬送装置と、容器の口部を封止すべく前記搬送装置の搬送経路上の所定位置に配置された密栓装置とを備え、容器の内部を陽圧化した状態で口部が封止される密栓ユニットに関する。   The present invention comprises a transport device for transporting a container and a sealing device disposed at a predetermined position on the transport path of the transport device so as to seal the mouth of the container, and the inside of the container is positively pressurized It relates to a sealing plug unit whose mouth is sealed.

この種の密栓ユニットに関連する先行技術文献情報として下記に示す特許文献１がある。この特許文献１では、省資源や軽量化などの目的で薄肉化された容器が、内容物の充填及び口部を封止後に、内容物液体の収縮などに起因する容器内の減圧によって変形する現象を防ぐ目的で、容器の封止時に数滴の液体窒素を口部内に封入する装置が提案されている。   There exists patent document 1 shown below as prior art document information relevant to this kind of sealing plug unit. In Patent Document 1, a container thinned for the purpose of saving resources or reducing the weight is deformed by the reduced pressure in the container due to the shrinkage of the contents liquid after filling the contents and sealing the mouth. In order to prevent the phenomenon, an apparatus has been proposed in which several drops of liquid nitrogen are sealed in the mouth when the container is sealed.

特許文献１による装置では、容器内に減圧が生じても、封止後に気化する液体窒素によって減圧が相殺されることで、減圧程度が弱まる或いは若干の加圧状態となるため、容器が薄肉化されており、補強された特別な容器形状でなくても、容器の変形が生じ難くなるとされている。   In the apparatus according to Patent Document 1, even if decompression occurs in the container, the decompression is offset by the liquid nitrogen vaporized after sealing, so that the degree of decompression is weakened or is slightly pressurized, so the container is thinned. Even if the shape of the container is not reinforced, the container is hardly deformed.

特開平６−２６３１９０号公報（０００２〜０００５段落、図１）JP-A-6-263190 (paragraphs 0002 to 0005, FIG. 1)

しかし、液体窒素は沸点が−１９６℃の超低温物質であり、注入または滴下された液体窒素は内容物と接触すると瞬時に気化・突沸するので、特許文献１に記された密栓ユニットでは、液体窒素の充填量にバラツキが生じ易く、均一な陽圧化状態を安定的に得ることが難いという問題があった。   However, liquid nitrogen is an ultra-low temperature substance having a boiling point of −196 ° C., and liquid nitrogen injected or dropped instantaneously vaporizes and bumps when it comes into contact with the contents. There is a problem in that the filling amount of the resin tends to vary, and it is difficult to stably obtain a uniform positive pressure state.

そこで、本発明の目的は、上に例示した従来技術が与える課題に鑑み、比較的簡単に均一な陽圧化状態を得ることが可能な密栓ユニットを提供することにある。   Accordingly, an object of the present invention is to provide a hermetic plug unit that can obtain a uniform positive pressure state relatively easily in view of the problems given by the conventional technique exemplified above.

本発明による密栓ユニットの特徴構成は、
樹脂で形成されている容器を搬送する搬送装置と、前記搬送装置の搬送経路上の所定位置に位置する容器の口部を封止するための密栓装置とを有する密栓ユニットであって、
前記密栓装置と少なくとも前記所定位置に位置する容器とを包囲する気圧筐体と、
少なくとも前記密栓装置による封止操作時に前記気圧筐体の内部を陽圧化する加圧手段と、を備えている点にある。
The characteristic configuration of the sealing unit according to the present invention is as follows.
A sealing device having a transporting device for transporting a container formed of resin and a sealing device for sealing a mouth of a container located at a predetermined position on a transport path of the transporting device,
A pressure housing surrounding the sealing device and at least the container located at the predetermined position;
And a pressurizing unit that positively pressurizes the interior of the atmospheric pressure housing during the sealing operation by the sealing device.

上記の特徴構成を備えた密栓ユニットでは、超低温物質の液体窒素などは用いず、密栓装置と封止する容器とだけを包囲可能な比較的小さな気圧筐体と、少なくとも密栓装置による封止操作時に、気圧筐体の内部を陽圧化する加圧手段とを設ければよいので、比較的小規模の装置によって簡単に、容器の内部に確実で均一な陽圧化状態を得ることができる。   In the sealing unit having the above-described characteristic configuration, liquid nitrogen, which is an ultra-low temperature substance, is not used, a relatively small pressure casing that can surround only the sealing device and the container to be sealed, and at least during sealing operation by the sealing device Since it is sufficient to provide a pressurizing means for positively pressurizing the inside of the atmospheric pressure housing, a positive and uniform positive pressure state can be easily obtained inside the container with a relatively small-scale apparatus.

本発明の他の特徴構成は、前記気圧筐体が、封止前の容器を受け入れる搬入開口部と、封止後の容器を排出するための搬出開口部と、容器の通過を許しつつ前記搬入開口部及び前記搬出開口部を閉鎖する閉鎖手段とを備えており、前記閉鎖手段は、容器の前記通過によって弾性的に開口するスリット部を有する点にある。   Another feature of the present invention is that the atmospheric pressure housing includes a carry-in opening for receiving a container before sealing, a carry-out opening for discharging the container after sealing, and the carry-in while allowing the container to pass through. And an opening and a closing means for closing the carry-out opening. The closing means has a slit portion that is elastically opened by the passage of the container.

本構成であれば、基本的に搬入開口部及び搬出開口部は閉鎖手段によって閉鎖されており、容器が閉鎖手段を通過する際にも、閉鎖手段のスリット部が容器の外形に応じて弾性的に開口することで、閉鎖手段と容器との協働によって搬入開口部及び搬出開口部の閉鎖状態は維持されるので、容器の出入りを許し、且つ、少なくとも密栓装置による封止操作時に閉鎖される複雑な構造のシャッター機構などを設ける必要がなく、比較的簡単に均一な陽圧化状態を得ることができる。   In this configuration, the carry-in opening and the carry-out opening are basically closed by the closing means, and the slit portion of the closing means is elastic according to the outer shape of the container even when the container passes through the closing means. Since the closed state of the carry-in opening and the carry-out opening is maintained by the cooperation of the closing means and the container, the container is allowed to enter and exit and is closed at least during the sealing operation by the sealing device. There is no need to provide a shutter mechanism having a complicated structure, and a uniform positive pressure state can be obtained relatively easily.

本発明の他の特徴構成は、前記搬送装置が前記密栓装置を容器と等速度で移動させる点にある。   Another feature of the present invention is that the transport device moves the sealing device at a constant speed with respect to the container.

本構成であれば、密栓装置が容器と等速度で移動しながら容器を封止できるので、封止操作の瞬間にも搬送装置による容器の搬送を停止する必要がなくなり、結果的に処理効率を高めることができる。   With this configuration, since the container can be sealed while the sealing device moves at the same speed as the container, it is not necessary to stop the conveyance of the container by the conveyance device even at the moment of the sealing operation, resulting in improved processing efficiency. Can be increased.

本発明の他の特徴構成は、前記搬送装置は軸芯回りで回転駆動される回転式搬送装置によって構成されており、
前記回転式搬送装置には、容器を支持する複数の支持手段と、各支持手段に対応した前記密栓装置とが周方向に沿って連設されている点にある。 In another aspect of the present invention, the transport device is constituted by a rotary transport device that is driven to rotate about an axis.
The rotary transport device is characterized in that a plurality of support means for supporting the container and the sealing device corresponding to each support means are provided in a line along the circumferential direction.

本構成であれば、先ず上流側から供給される容器を支持し、次に搬送と密栓装置による封止とを同時に行い、最後に下流側に渡すという一連の動作を連続的に且つ円滑に行うことが可能となるので、密栓装置が搬送装置の直線的な搬送経路に沿って往復移動しながら封止する構成などに比べて、高い処理効率を得ることができる。   In this configuration, a series of operations are performed continuously and smoothly, first supporting a container supplied from the upstream side, then simultaneously carrying and sealing with a sealing device, and finally passing to the downstream side. Therefore, higher processing efficiency can be obtained as compared with a configuration in which the sealing device is sealed while reciprocating along the linear transport path of the transport device.

本発明の他の特徴構成は、前記気圧筐体が、容器の出入りを許し、且つ、少なくとも前記密栓装置による封止操作時に閉鎖される出入口として、容器の断面形状と対応する開口部を備えており、前記所定位置以外に位置する容器が前記開口部を閉鎖している間に前記封止操作が実施される点にある。   In another aspect of the present invention, the atmospheric pressure housing includes an opening corresponding to the cross-sectional shape of the container as an inlet / outlet that allows the container to enter and exit and is closed at least during the sealing operation by the sealing device. In addition, the sealing operation is performed while a container located at a position other than the predetermined position closes the opening.

本構成であれば、気圧筐体に設ける容器の出入口を容器の断面形状と対応させることで、気圧筐体に対する容器の出入を可能にし、且つ、搬送中の容器そのものによって出入口を閉鎖することができ、その閉鎖中に封止操作を実施すればよいので、容器の出入りを許し、且つ、少なくとも密栓装置による封止操作時に閉鎖される複雑な構造のシャッター機構などを設ける必要がなく、比較的簡単に均一な陽圧化状態を得ることができる。   With this configuration, the entrance / exit of the container provided in the atmospheric pressure housing corresponds to the cross-sectional shape of the container, thereby allowing the container to enter and exit from the atmospheric pressure housing and closing the entrance / exit by the container being transported itself. Since it is only necessary to perform a sealing operation during the closing, it is not necessary to provide a shutter mechanism having a complicated structure that allows the container to enter and exit, and is closed at least during the sealing operation by the sealing device. A uniform positive pressure state can be easily obtained.

以下に本発明を実施するための形態について図面を参照しながら説明する。
（第１実施形態）
図１及び図２に示す密栓ユニット５０Ａは、容器１の内部に飲料などの内容物を充填するフィラー（不図示）の下流側に設けられており、内容物を充填されたボトル状の容器１を連続的に搬送する搬送装置３と、容器１の口部１Ａをキャップ２によって封止するための密栓装置５とを有する。容器１は、ポリエチレンテレフタレート、或いはポリプロピレンやポリエチレンなどの樹脂で形成されている。 EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated, referring drawings.
(First embodiment)
1 and 2 is provided on the downstream side of a filler (not shown) that fills a container 1 with a content such as a beverage, and is a bottle-shaped container 1 filled with the content. The container 3 and the cap 1 for sealing the mouth 1A of the container 1 with the cap 2. The container 1 is made of polyethylene terephthalate or a resin such as polypropylene or polyethylene.

搬送装置３は、縦姿勢の容器１をネックリングの下部付近で支持する多数のグリッパ４と、グリッパ４を図１の白い矢印方向に沿って搬送するコンベア装置（不図示）とを有する。
このコンベア装置は、容器１を搬送経路上の所定位置（Ｘ）に一定時間だけ静止させるように構成されており、密栓装置５は、容器１が所定位置（Ｘ）に静止している間に容器１の口部１Ａを封止する。 The transport device 3 includes a number of grippers 4 that support the container 1 in a vertical position near the lower portion of the neck ring, and a conveyor device (not shown) that transports the grippers 4 along the direction of the white arrow in FIG.
The conveyor device is configured to keep the container 1 stationary at a predetermined position (X) on the conveyance path for a predetermined time, and the sealing device 5 is configured so that the container 1 is stationary at the predetermined position (X). The mouth 1A of the container 1 is sealed.

密栓ユニット５０Ａは、密栓装置５と少なくとも所定位置（Ｘ）に位置する容器１とを包囲する封止チャンバー７（気圧筐体の一例）を備えている。
封止チャンバー７は、封止される前の容器１を受け入れる搬入開口部７Ａと、キャップ２で封止された容器１を排出するための搬出開口部７Ｂと、グリッパ４の通過を許すために概して水平に延びたスリット部７Ｓとを有する。 The sealing plug unit 50A includes a sealing chamber 7 (an example of a pneumatic housing) that surrounds the sealing device 5 and the container 1 positioned at least at a predetermined position (X).
The sealing chamber 7 is for allowing passage of a carry-in opening 7A for receiving the container 1 before being sealed, a carry-out opening 7B for discharging the container 1 sealed with the cap 2, and the gripper 4. The slit portion 7S extends generally horizontally.

搬入開口部７Ａは、キャップ２で封止前の容器１の中心軸を含む断面形状と概して合致する形状とされており、搬出開口部７Ｂは、キャップ２で封止後の容器１の中心軸を含む断面形状と概して合致する形状とされている。   The carry-in opening 7A has a shape that generally matches the cross-sectional shape including the central axis of the container 1 before sealing with the cap 2, and the carry-out opening 7B has the central axis of the container 1 after sealing with the cap 2. The shape generally matches the cross-sectional shape including

少なくともスリット部７Ｓの付近は、上下からグリッパ４の移動経路に向かって延びたゴムなどの一対の弾性体部（不図示）で構成されており、これらの弾性体部は上下に互いに押付けられることで基本的に閉じられており、グリッパ４はこれらの弾性体部をこじ開けながら横向きに通過するので、グリッパ４が通過した直後に再びスリット部７Ｓは弾性体部によって閉じられる。   At least the vicinity of the slit portion 7S is composed of a pair of elastic body portions (not shown) such as rubber extending from above and below toward the movement path of the gripper 4, and these elastic body portions are pressed against each other up and down. Since the gripper 4 passes sideways while opening the elastic body portions, the slit portion 7S is closed again by the elastic body portions immediately after the gripper 4 passes.

封止チャンバー７の壁面の一部には、ブロワ１０（加圧手段の一例）から送られる空気を封止チャンバー７の内部に取り込むための配管７Ｃと、封止チャンバー７の内部の気圧を検出する圧力センサＰＳが取付けられている。   On a part of the wall surface of the sealing chamber 7, a pipe 7 </ b> C for taking air sent from the blower 10 (an example of a pressurizing unit) into the sealing chamber 7 and the pressure inside the sealing chamber 7 are detected. A pressure sensor PS is attached.

１つの容器１が密栓装置５の直下の所定位置（Ｘ）に位置する間は、搬入開口部７Ａは上流側の封止前の他の容器１によって封鎖されており、且つ、搬出開口部７Ｂは下流側の封止後の他の容器１によって封鎖されているように、搬入開口部７Ａ及び搬出開口部７Ｂの位置関係が構成されている。   While one container 1 is positioned at a predetermined position (X) immediately below the sealing device 5, the carry-in opening 7A is sealed by another container 1 before sealing on the upstream side, and the carry-out opening 7B. The positional relationship between the carry-in opening 7 </ b> A and the carry-out opening 7 </ b> B is configured so as to be sealed by another container 1 after sealing on the downstream side.

その結果、少なくとも封止される容器１が所定位置（Ｘ）に位置する間は、封止チャンバー７内の密閉性が確立され、封止チャンバー７の内部がブロワ１０から送られる空気の作用によって例えば０．１ｋｇｗ／ｃｍ2以上に陽圧化されるため、密栓装置５によって封止された容器１の内部も０．１ｋｇｗ／ｃｍ2以上に陽圧化された状態とできる。 As a result, at least while the container 1 to be sealed is located at the predetermined position (X), the sealing property in the sealing chamber 7 is established, and the inside of the sealing chamber 7 is caused by the action of air sent from the blower 10. For example, since the positive pressure is increased to 0.1 kgw / cm 2 or more, the inside of the container 1 sealed by the sealing device 5 can also be set to a positive pressure of 0.1 kgw / cm 2 or more.

（第２実施形態）
図３及び図４に示す第２実施形態による密栓ユニット５０Ｂでは、搬入開口部７Ａと搬出開口部７Ｂとに容器１の通過を許し、且つ、容器１の通過中以外は自動的に閉じられる弾性材料製の遮蔽手段８が設けられている。 (Second Embodiment)
In the sealing plug unit 50B according to the second embodiment shown in FIG. 3 and FIG. 4, the elasticity that allows the container 1 to pass through the carrying-in opening 7A and the carrying-out opening 7B and is automatically closed except when the container 1 is passing. A shielding means 8 made of material is provided.

遮蔽手段８は、搬入開口部７Ａや搬出開口部７Ｂの縁部から容器１の中心線付近に向かって延びる複数の板状のシールド部材で構成されている。これらのシールド部材の間には容器１の通過に際して容器１の断面形状に応じて弾性的に開口するスリット部が形成されている。容器１の通過中以外は、これらのシールド部材の先端側が互いに弾性的に当接或いは近接することで、搬入開口部７Ａ及び搬出開口部７Ｂが閉じられる。   The shielding means 8 is composed of a plurality of plate-like shield members extending from the edge of the carry-in opening 7A and the carry-out opening 7B toward the vicinity of the center line of the container 1. Between these shield members, there is formed a slit portion that opens elastically according to the cross-sectional shape of the container 1 when the container 1 passes through. Except during the passage of the container 1, the carry-in opening 7A and the carry-out opening 7B are closed by elastically abutting or approaching the distal ends of these shield members.

（第３実施形態）
図５に示す第３実施形態による密栓ユニット５０Ｃは、上下に延びた軸芯Ｙ回りで回転駆動される回転式搬送装置３Ａ（搬送装置の一例）を備えている。回転式搬送装置３Ａの外周付近には、容器１をネックリングの下部付近で支持する複数のグリッパ４（支持手段の一例）と、グリッパ４と同数の密栓装置５とが周方向に沿って連設されている。個々の密栓装置５は、各グリッパ４の真上に配置されており、モータなどの駆動手段（不図示）によって、容器１と等速度で回転移動される。 (Third embodiment)
A sealing plug unit 50C according to the third embodiment shown in FIG. 5 includes a rotary transfer device 3A (an example of a transfer device) that is driven to rotate about an axis Y extending vertically. Near the outer periphery of the rotary transfer device 3A, a plurality of grippers 4 (an example of support means) for supporting the container 1 in the vicinity of the lower portion of the neck ring and the same number of sealing devices 5 as the grippers 4 are connected along the circumferential direction. It is installed. The individual sealing device 5 is disposed immediately above each gripper 4 and is rotated and moved at the same speed as the container 1 by a driving means (not shown) such as a motor.

回転式搬送装置３Ａの上流側には、回転式のフィラー３０が設けられており、フィラー３０によって内部に飲料などを充填された容器１は、フィラー３０と回転式搬送装置３Ａの間に介装されたスターホイール４０によって、１個ずつ連続的に回転式搬送装置３Ａに供給される。   A rotary filler 30 is provided on the upstream side of the rotary transfer device 3A, and the container 1 filled with a beverage or the like by the filler 30 is interposed between the filler 30 and the rotary transfer device 3A. The supplied star wheel 40 is continuously supplied to the rotary transfer device 3A one by one.

回転式搬送装置３Ａは、充填済みの容器１を支持したグリッパ４を、図の場合には平面視で反時計回りに移動させるが、この移動中に、対応する密栓装置５によって封止が実施される。
キャップ２によって封止された容器１は、回転式搬送装置３Ａの下流側に隣接配置された別のスターホイール（不図示）によって下流側の箱詰め装置などに渡される。 The rotary transfer device 3A moves the gripper 4 supporting the filled container 1 counterclockwise in a plan view in the case of the figure. During this movement, sealing is performed by the corresponding sealing device 5. Is done.
The container 1 sealed by the cap 2 is delivered to a downstream boxing device or the like by another star wheel (not shown) arranged adjacent to the downstream side of the rotary transfer device 3A.

密栓ユニット５０Ｃは、回転式搬送装置３Ａの全体を包囲する封止チャンバー７を備えている。封止チャンバー７は、回転式搬送装置３Ａに設けられた全ての密栓装置５及びグリッパ４と、グリッパ４に支持された全ての容器１を包囲している。   The sealing plug unit 50C includes a sealing chamber 7 that surrounds the entire rotary transfer device 3A. The sealing chamber 7 surrounds all the sealing devices 5 and the grippers 4 provided in the rotary transfer device 3 </ b> A and all the containers 1 supported by the grippers 4.

概して有底円筒状の封止チャンバー７の壁面の一部には、ブロワ１０から送られる空気を封止チャンバー７の内部に受け入れるための配管７Ｃと、封止チャンバー７の内部の気圧を検出する圧力センサ（不図示）とが設けられており、第１及び第２実施形態と同様に、封止チャンバー７の内部は、ブロワ１０から送られる空気の作用によって回転式搬送装置３Ａの稼動中は基本的に常に陽圧化されている。   A pipe 7C for receiving the air sent from the blower 10 into the inside of the sealing chamber 7 and the atmospheric pressure inside the sealing chamber 7 are detected on a part of the wall surface of the bottomed cylindrical sealing chamber 7. A pressure sensor (not shown) is provided, and as in the first and second embodiments, the inside of the sealing chamber 7 is under operation of the rotary transfer device 3A by the action of air sent from the blower 10. Basically it is always positive pressure.

封止チャンバー７の壁面の一部には、スターホイール４０から渡された封止前の容器１を受け入れるスリット状の搬入開口部７Ｄと、キャップ２で封止された容器１を下流側のスターホイールに向けて排出するための搬出開口部（不図示）とが形成されている。   In a part of the wall surface of the sealing chamber 7, a slit-like loading opening 7 </ b> D that receives the unsealed container 1 delivered from the star wheel 40, and the container 1 sealed with the cap 2 is connected to the downstream star. A carry-out opening (not shown) for discharging toward the wheel is formed.

搬入開口部７Ｄと搬出開口部には、ほぼ第２実施形態と同様に、容器１の通過を許し、且つ、容器１の通過中以外は自動的に閉じられることで、封止チャンバー７内の陽圧状態を保持する弾性材料製の遮蔽手段（不図示）が設けられている。   The carry-in opening 7D and the carry-out opening are allowed to pass through the container 1 and are automatically closed except when the container 1 is passing, as in the second embodiment. Shielding means (not shown) made of an elastic material that maintains a positive pressure state is provided.

封止チャンバー７の内部には、上流側のスターホイール４０や下流側のスターホイールの一部も包囲されるため、封止チャンバー７の壁面の一部には、封止チャンバー７内の陽圧状態を保持しつつ、これらのスターホイールの外周部位の相対移動を許すための横向きに延びたスリット７Ｅが形成されている。   Since the sealing chamber 7 includes the upstream star wheel 40 and a part of the downstream star wheel, the positive pressure in the sealing chamber 7 is included in a part of the wall surface of the sealing chamber 7. While maintaining the state, a laterally extending slit 7E is formed to allow relative movement of the outer peripheral portion of these star wheels.

〔別実施形態〕

It is good also as a structure which controls.

〈３〉ブロワ１０の代わりに、クリーンルームを構成するラミナーフローを加圧手段として利用してもよい。 <3> Instead of the blower 10, a laminar flow constituting a clean room may be used as a pressurizing means.

〈４〉また、ブロワ１０の代わりに、封止チャンバー７と気体流路で接続された予備高圧チャンバー（不図示）と、この予備高圧チャンバーを常に一定以上の高圧に保持するコンプレッサ（不図示）と、容器１が所定位置（Ｘ）に位置する間だけ気体流路の途中に介装した開閉弁（不図示）を開放する制御装置とを加圧手段として設けてもよい。 <4> Further, instead of the blower 10, a preliminary high-pressure chamber (not shown) connected to the sealing chamber 7 by a gas flow path, and a compressor (not shown) that always keeps the preliminary high-pressure chamber at a certain level or higher. And a controller for opening an on-off valve (not shown) interposed in the middle of the gas flow path only while the container 1 is located at the predetermined position (X) may be provided as the pressurizing means.
