以下、添付図面を参照しながら本発明の好適な実施形態を説明する。   Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

図１、図２は、本発明の好適な実施形態のキャップ装着装置（或いは、キャップ付製品の製造装置）の構成を概略的に示す側面図、平面図である。キャップ装着装置１００は、フランジを有する口部を備えた容器（例えば、ビール樽）１０の該口部に熱収縮性キャップ３４を装着する装置として構成されている。熱収縮性キャップとしては、例えば、その全体が熱収縮性材料で構成されたものや、一部が熱収縮性材料で構成されたもの（例えば、天板部が紙等の非熱収縮性材料で構成され、筒部が熱収縮性材料で構成されたもの）を挙げることができる。熱収縮性キャップの好適な材質としては、例えば、ＰＥＴ（ポリエチレンテレフタレート）又はポリスチレンを挙げることができる。熱収縮性キャップは、熱が加えられることによって収縮して口部に固定されることが知られている。例えば図３に例示的に示すように、熱収縮性キャップ３４は、天板部（典型的には、円盤形状を有する）３４ａと、その縁からスカート状に延びた筒部（典型的には、円筒形状を有する）３４ｂとを有し、天板部３４ａの反対側の端部が開口していて、この開口した端部（開口端部）に口部が挿入されるようにして口部に被せられる。   1 and 2 are a side view and a plan view schematically showing a configuration of a cap mounting device (or a device for manufacturing a product with a cap) according to a preferred embodiment of the present invention. The cap mounting device 100 is configured as a device that mounts the heat-shrinkable cap 34 on the mouth portion of a container (for example, a beer barrel) 10 having a mouth portion having a flange. As a heat-shrinkable cap, for example, one that is entirely composed of a heat-shrinkable material, or one that is partially composed of a heat-shrinkable material (for example, a non-heat-shrinkable material such as a top plate is paper) And the cylindrical portion is made of a heat-shrinkable material). Suitable materials for the heat-shrinkable cap include, for example, PET (polyethylene terephthalate) or polystyrene. It is known that the heat-shrinkable cap contracts and is fixed to the mouth portion when heat is applied. For example, as shown in FIG. 3, the heat-shrinkable cap 34 includes a top plate portion (typically having a disk shape) 34a and a cylindrical portion (typically having a skirt shape extending from the edge). 34b having a cylindrical shape), and an end portion on the opposite side of the top plate portion 34a is opened, and the mouth portion is inserted into the opened end portion (open end portion). Be put on.

キャップ装着装置１００は、例えば、コンベア２０、操作機構３０、プレヒータ４０、メインヒータ５０を備えている。キャップ装着装置１００のコンベア２０には、典型的には、ビール等の液体製品が充填された容器１０が送り込まれる。   The cap mounting apparatus 100 includes, for example, a conveyor 20, an operation mechanism 30, a preheater 40, and a main heater 50. A container 10 filled with a liquid product such as beer is typically fed into the conveyor 20 of the cap mounting apparatus 100.

コンベア２０による容器１０の搬送経路において、操作機構３０が容器１０の口部１２に熱収縮性キャップ３４を被せ、次いで、プレヒータ４０が熱収縮性キャップ３４の開口端部付近の少なくとも一部を加熱して部分的に収縮させる。この収縮によって熱収縮性キャップ３４の開口端部の径が小さくなるので、熱収縮性キャップ３４の天板部３４ａは、口部１２の上端に押し付けられる方向に力を受ける。これにより、口部１２からの天板部３４ａの浮き上がりが防止される。次いで、メインヒータ５０は、プレヒータ４０による加熱によって部分的に収縮した熱収縮キャップ３４を更に過熱して全体的に収縮させる。これによって、熱収縮キャップ３４が口部１２に全体的に密着する。   In the transport path of the container 10 by the conveyor 20, the operation mechanism 30 covers the mouth 12 of the container 10 with the heat-shrinkable cap 34, and then the preheater 40 heats at least a part near the opening end of the heat-shrinkable cap 34. And partially shrink. Since the diameter of the opening end portion of the heat-shrinkable cap 34 is reduced by this shrinkage, the top plate portion 34 a of the heat-shrinkable cap 34 receives a force in a direction in which it is pressed against the upper end of the mouth portion 12. Thereby, the top plate part 34a is prevented from being lifted from the mouth part 12. Next, the main heater 50 further superheats the heat shrink cap 34 partially shrunk by the heating by the pre-heater 40 and shrinks it as a whole. As a result, the heat shrink cap 34 adheres to the mouth portion 12 as a whole.

ここで、プレヒータ４０による熱収縮性キャップ３４の加熱の際、好ましくは、更に、メインヒータ５０による熱収縮キャップ３４の加熱の際に、熱収縮キャップ３４を口部１２に対して押し付けることが好ましい。これにより、熱収縮性キャップ３４が口部１２から浮き上がることがより確実に防止される。また、例えば、プレヒータ４０が熱風によって熱収縮性キャップ３４を加熱する構成を有する場合になどにおいて、熱風によって熱収縮性キャップ３４が口部１２から飛ばされることを防止することができる。図１、図２に示す構成例では、プレヒータ４０による熱収縮性キャップ３４の加熱の際及びメインヒータ５０による熱収縮キャップ３４の加熱の際に、押し付け機構６０によって熱収縮性キャップ３４を口部１２に押し付けている。   Here, when the heat-shrinkable cap 34 is heated by the preheater 40, preferably, when the heat-shrinkable cap 34 is heated by the main heater 50, the heat-shrinkable cap 34 is preferably pressed against the mouth portion 12. . This more reliably prevents the heat-shrinkable cap 34 from floating from the mouth portion 12. Further, for example, when the preheater 40 has a configuration in which the heat-shrinkable cap 34 is heated by hot air, the heat-shrinkable cap 34 can be prevented from being blown from the mouth portion 12 by hot air. In the configuration example shown in FIGS. 1 and 2, when the heat-shrinkable cap 34 is heated by the preheater 40 and when the heat-shrinkable cap 34 is heated by the main heater 50, the pressing mechanism 60 causes the heat-shrinkable cap 34 to be attached to the mouth portion. 12 is pressed.

取り扱う容器の寸法、特に高さ寸法が変わる場合には、プレヒータ４０及びメインヒータ５０等をその容器の寸法に応じて移動させる必要がある。この作業は、一般に型替え作業と呼ばれている。型替え作業を容易にするためには、プレヒータ４０とメインヒータ５０とが相互に連結されていることが好ましい。この場合、双方を一度に移動させて型替え作業を完了することができる。図２に示す例では、プレヒータ４０は、連結部材４５によってメインヒータ５０に連結されている。   When the size of the container to be handled, particularly the height dimension changes, it is necessary to move the preheater 40, the main heater 50, etc. according to the dimensions of the container. This operation is generally called a mold change operation. In order to facilitate the mold changing operation, it is preferable that the preheater 40 and the main heater 50 are connected to each other. In this case, the mold changing operation can be completed by moving both of them at once. In the example shown in FIG. 2, the preheater 40 is connected to the main heater 50 by a connecting member 45.

以下、図３〜図６をも参照しながらキャップ装着装置１００の動作及びキャップ付製品の製造方法を更に詳細に説明する。図３は、操作機構３０によって容器１０の口部１２に熱収縮性キャップ３４を被せた状態を模式的に示している。操作機構３０は、搬送機構３２によって連続的に搬送されてくる熱収縮性キャップ３４を吸着機構によって吸着して受け取って、これを容器１０の口部１２に被せる。   Hereinafter, the operation of the cap mounting apparatus 100 and the method for manufacturing a product with a cap will be described in more detail with reference to FIGS. FIG. 3 schematically illustrates a state in which the heat shrinkable cap 34 is put on the mouth portion 12 of the container 10 by the operation mechanism 30. The operation mechanism 30 receives the heat-shrinkable cap 34 continuously conveyed by the conveyance mechanism 32 by adsorption by the adsorption mechanism, and puts it on the mouth portion 12 of the container 10.

図４、図５は、容器１０の口部１２に被せられた熱収縮性キャップ３４の開口端部付近３４ｃの少なくとも一部（例えば、約半分）をプレヒータ４０によって加熱している状態を模式的に示している。プレヒータ４０によって加熱する部分の大きさや加熱時間等は、熱収縮性キャップ３４の材質、形状、寸法等によって適宜変更しうるが、熱収縮性キャップ３４の開口端部付近の収縮によって天板部３４ａが口部１２の上面に押し付けられるように調整されるべきである。   4 and 5 schematically show a state in which at least a part (for example, about half) of the vicinity of the open end 34c of the heat-shrinkable cap 34 placed on the mouth 12 of the container 10 is heated by the preheater 40. FIG. It shows. The size of the portion heated by the preheater 40, the heating time, and the like can be changed as appropriate depending on the material, shape, dimensions, and the like of the heat-shrinkable cap 34. Should be adjusted to be pressed against the upper surface of the mouth 12.

プレヒータ４０による熱収縮性キャップ３４の開口端部付近の全部又は一部の加熱によって、熱収縮性キャップ３４の開口端部付近の径が小さくなるので、該開口端部付近の部分が熱収縮性キャップ３４のフランジ１２ａの下方を締め付けるようにして、熱収縮性キャップ３４の天板部３４ａが口部１２の上端に押し付けられる。これによって、口部１２からの熱収縮性キャップ３４の浮き上がりが防止された状態で、続くメインヒータ５０による加熱がなされることになる。   Heating all or part of the heat shrinkable cap 34 near the opening end by the preheater 40 reduces the diameter of the heat shrinkable cap 34 near the opening end, so that the portion near the opening end is heat shrinkable. The top plate portion 34 a of the heat-shrinkable cap 34 is pressed against the upper end of the mouth portion 12 so as to tighten the lower portion of the flange 12 a of the cap 34. Thus, the subsequent heating by the main heater 50 is performed in a state in which the heat-shrinkable cap 34 is prevented from being lifted from the mouth portion 12.

プレヒータ４０は、コンベア２０による容器１０の搬送経路を塞がないように、例えば、図５に例示的に示すように、コンベア２０の側方に配置されることが好ましい。ここで、ビール樽のように容器１０が口部１２の周りに円筒部（図５では、断面（ハッチング部）を付した部分）を有する場合には、プレヒータ４０は、コンベア２０の側方から口部１２の側面（熱収縮性キャップ３４の開放端部付近）に向けて斜め下方に熱風を吹き付けるように構成されることが好ましい。   The preheater 40 is preferably arranged on the side of the conveyor 20 as illustrated in FIG. 5, for example, so as not to block the conveyance path of the containers 10 by the conveyor 20. Here, when the container 10 has a cylindrical portion (portion with a cross section (hatched portion in FIG. 5)) around the mouth portion 12 like a beer barrel, the preheater 40 is from the side of the conveyor 20. It is preferable that hot air is blown obliquely downward toward the side surface of the mouth portion 12 (near the open end of the heat-shrinkable cap 34).

プレヒータ４０は、典型的には、熱風を熱収縮性キャップ３４の開口端部付近の所定部分に吹き付けることによって当該部分を加熱するように構成されうるが、例えば、該所定部分に赤外線等を照射する構成を採用することもできる。図５には、プレヒータ４０の一部の構成例として、熱風を噴出すノズルが示されている。   The preheater 40 can typically be configured to heat a predetermined portion near the opening end of the heat-shrinkable cap 34 by blowing hot air. For example, the predetermined portion is irradiated with infrared rays or the like. It is also possible to adopt a configuration that does this. FIG. 5 shows a nozzle that ejects hot air as a configuration example of a part of the preheater 40.

図６は、プレヒータ４０による部分的な加熱によって部分的に収縮した熱収縮性キャップ３４をメインヒータ５０によって更に加熱して全体的に収縮させる状態を示している。メインヒータ５０は、典型的には、熱収縮性キャップ３４の全体を加熱するように構成されうるが、プレヒータ４０によって既に加熱され十分に収縮している部分については加熱しなくてもよい。メインヒータ５０は、例えば、容器１０の口部１２に対して上方から熱風を吹き付けるように構成されてもよいし、赤外線等を照射するように構成されてもよい。   FIG. 6 shows a state in which the heat-shrinkable cap 34 partially contracted by partial heating by the preheater 40 is further heated by the main heater 50 to be contracted as a whole. The main heater 50 may typically be configured to heat the entire heat-shrinkable cap 34, but the portion that has already been heated and sufficiently contracted by the pre-heater 40 may not be heated. For example, the main heater 50 may be configured to blow hot air from above on the mouth portion 12 of the container 10 or may be configured to irradiate infrared rays or the like.

キャップ装着装置１００による以上のようなキャッピング処理を経てキャップ付製品（例えば、出荷用ビール製品）が製造される。なお、キャップが付された製品は、典型的には、出荷検査がなされ、その後に出荷される。   A capped product (for example, a beer product for shipping) is manufactured through the capping process as described above by the cap mounting apparatus 100. Note that a product with a cap is typically subjected to a shipping inspection and then shipped.

プレヒータ４０とメインヒータ５０の双方で熱風を利用する方式を採用する場合には、単一のヒータからそれぞれプレヒータ用のノズル及びメインヒータ用のノズルに熱風を供給する構成を採用してもよい。   In the case of adopting a system that uses hot air in both the preheater 40 and the main heater 50, a configuration in which hot air is supplied from a single heater to the nozzle for the preheater and the nozzle for the main heater may be adopted.

以上のように、容器の口部に熱収縮性キャップを被せた後に、まず、第１段階において、熱収縮性キャップの開口端部付近の全部又は一部を加熱して熱収縮性キャップを部分的に収縮させ、その後、第２段階において、熱収縮性キャップを更に加熱して全体的に収縮させることにより、容器の口部からの熱収縮性キャップの浮き上がりを防止することができる。これにより、キャッピングの不良を低減し、製造効率を高めることができる。   As described above, after covering the mouth of the container with the heat-shrinkable cap, first, in the first stage, all or part of the vicinity of the opening end of the heat-shrinkable cap is heated to partially cover the heat-shrinkable cap. Then, in the second stage, the heat-shrinkable cap is further heated to shrink as a whole, thereby preventing the heat-shrinkable cap from being lifted from the mouth of the container. Thereby, the capping defect can be reduced and the manufacturing efficiency can be increased.
