食品衛生上、ジュースや牛乳などの液体食品などを充填する容器は、衛生的に良好な雰囲気下で、その空容器に液体を充填する必要がある。
その様な食品を連続的に充填する充填装置では、食品の充填装置（チャンバー）内は衛生性のために内部にクリーンエアを送り、外気圧よりも圧力の高い状態（陽圧）を保ち、絶えず、装置（チャンバー）内部からクリーンエアを漏らすことによって、外部雰囲気から空気が装置（チャンバー）内部に浸入しないようにしている。しかし、屋根型紙容器用充填装置には、空容器（カートン）入口及び充填済み容器（製品）出口が大きく開放されていて、気密性が良くない。従って、大型のクリンエアー送風装置（クリーンエアシステム）による強力な送風によってチャンバー内の陽圧を確保している。
この為に、このクリーンエアシステムの送風機は大電力を消費し騒音が大きい。内部ヘフィルターも大型でメンテナンスが大変でコストもかかる。
これに対して、充填装置カバー・ドア等の気密性を高める。また、樹脂製「のれん」を容器の入口や製品の出口に設置する等の工夫がなされている。
本発明は、上記の必要性、切望に応えるものであり、装置内部チャンバーの気密性が高く、低コストであって廉価に維持することができ、省エネルギーでもある液体充填装置を提供することを目的とする。

In such a filling device that continuously fills food, the food filling device (chamber) sends clean air to the inside for hygiene and maintains a higher pressure (positive pressure) than the external pressure, By constantly leaking clean air from the inside of the apparatus (chamber), air is prevented from entering the inside of the apparatus (chamber) from the outside atmosphere. However, an empty container (carton) inlet and a filled container (product) outlet are largely open in the roof-type paper container filling device, which is not airtight. Therefore, the positive pressure in the chamber is ensured by strong air blowing by a large clean air blowing device (clean air system).
For this reason, the blower of this clean air system consumes a large amount of power and is noisy. The internal filter is large and maintenance is expensive and expensive.
On the other hand, the air tightness of the filling device cover, door, etc. is enhanced. In addition, various measures have been taken, such as installing “goodwill” made of resin at the inlet of the container and the outlet of the product.
SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid filling apparatus that meets the above-described needs and desires, has a high airtightness of the chamber inside the apparatus, can be maintained at a low cost, and is energy-saving. And

入口ステーション及び出口ステーションには、それぞれ、搬送路を挟んで設けられる第１及び第２の回転扉と、回転扉の外側に設けられた壁とが配設され、
回転扉には、回転軸に対称に２枚の回転自在の遮蔽板が設けられ、
遮蔽板は、少なくとも搬送路の中央を超えて回転可能であるように板幅を持ち、
第１及び第２の回転扉の遮蔽板は、対向する際に他方の遮蔽板とお互いに接触するように連動し、
壁の内壁は、回転する遮蔽板の先端と近接しかつ接触しない形状を有する、
ことを特徴とする。

Inlet and outlet stations do not mean that the chamber seals its inlet and outlet for the purposes of this invention.
この発明の液体充填装置では、容器をチャンバー内に入れる入口ステーションと、密封された容器を排出する出口ステーションとを備える。
この入口ステーション及び出口ステーションには、それぞれ、搬送路を挟んで設けられる第１及び第２の回転扉と、回転扉の外側に設けられた壁とが配設され、回転扉には、回転軸に対称に２枚の回転自在の遮蔽板が設けられ、遮蔽板は、少なくとも搬送路の中央を超えて回転可能であるように板幅を持つ。
The liquid filling apparatus of the present invention includes an inlet station that puts a container into the chamber and an outlet station that discharges the sealed container.
Each of the entrance station and the exit station is provided with first and second revolving doors provided across the conveyance path, and a wall provided on the outside of the revolving door. Symmetrically , two rotatable shielding plates are provided, and the shielding plates have a plate width so that they can rotate at least beyond the center of the conveyance path.
上記構成を持つ回転扉では、回転扉付近の搬送路上に容器が存在しないとき、第１及び第２の回転扉の遮蔽板は、対向する際に他方の遮蔽板とお互いに接触し、チャンバーとその外側とを遮断し、外部雰囲気のチャンバーへの侵入を防止することができる。また、無用にチャンバー内の無菌エアの流出を防止することができる。
回転扉付近の搬送路上に容器が移動して回転扉に接近すると、遮蔽板が搬送路の中央を超えて回転可能であるように板幅を持つので、第１及び第２の回転扉の遮蔽板の前半分のそれぞれの板壁に容器が当たり、容器の圧力で及び／又は回転扉の回転力で、遮蔽板が容器の移動と共に回転する。
この回転する間は、チャンバーとその外側とが遮断されないが、遮蔽板と容器との隙間だけであるので、外部雰囲気のチャンバーへの侵入を最小限に抑え、また、チャンバー内の無菌エアの流出を最少化することができる。

In addition, the outflow of sterile air in the chamber can be prevented unnecessarily.
When the container moves on the transport path near the revolving door and approaches the revolving door, the shielding plate has a width so that it can rotate beyond the center of the transport path, so that the first and second revolving doors are shielded. The container hits each plate wall in the front half of the plate, and the shielding plate rotates with the movement of the container by the pressure of the container and / or by the rotational force of the rotary door.
During this rotation, the chamber and its outside are not blocked, but only the gap between the shielding plate and the container, so that the entry of the external atmosphere into the chamber is minimized, and the outflow of sterile air in the chamber Can be minimized.
回転扉付近の搬送路上から容器が離れる方向に移動すると、遮蔽板が回転軸に対して回転自在であるので、第１及び第２の回転扉の遮蔽板の後半分のそれぞれの板壁に容器が当たり、回転扉の自動回転力で、遮蔽板が容器の移動と共に回転する。
同様に、この回転する間は、チャンバーとその外側とが遮断されないが、遮蔽板と容器との隙間だけであるので、外部雰囲気のチャンバーへの侵入を最小限に抑え、また、チャンバー内の無菌エアの流出を最少化することができる。
When the container moves away from the conveyance path in the vicinity of the revolving door, the shielding plate is rotatable with respect to the rotation axis. The shielding plate rotates with the movement of the container by the automatic rotation force of the revolving door.
Similarly, during this rotation, the chamber and its outside are not blocked, but only the gap between the shielding plate and the container, so that the entry of the external atmosphere into the chamber is minimized, and the inside of the chamber is sterilized. Air outflow can be minimized.
回転扉付近の搬送路上から容器が離れると、第１及び第２の回転扉の遮蔽板は、対向する際に他方の遮蔽板とお互いに接触し、チャンバーとその外側とを遮断し、外部雰囲気のチャンバーへの侵入を防止することができる。また、無用にチャンバー内の無菌エアの流出を防止することができる。 When the container is separated from the conveyance path in the vicinity of the revolving door, the shielding plates of the first and second revolving doors come into contact with the other shielding plate when facing each other, blocking the chamber from the outside, and the external atmosphere. Can be prevented from entering the chamber. In addition, the outflow of sterile air in the chamber can be prevented unnecessarily.
この入口ステーション及び出口ステーションには、回転する遮蔽板の先端と近接しかつ接触しない形状を有する内壁を備える。
遮蔽板の回転する間及び、回転扉付近の搬送路上に容器が存在しないときも、チャンバーとその外側とを遮断し、外部雰囲気のチャンバーへの侵入を防止することができる。また、無用にチャンバー内の無菌エアの流出を防止することができる。
Each of the entrance station and the exit station includes an inner wall having a shape that is close to and does not contact the tip of the rotating shielding plate.
Even when the shielding plate is rotating and when there is no container on the conveyance path near the rotary door, the chamber and the outside thereof can be blocked to prevent the outside atmosphere from entering the chamber. In addition, the outflow of sterile air in the chamber can be prevented unnecessarily.
上述の様に、この回転扉構造によって、気密性の高いチャンバーは、小型で廉価で静かでメンテの楽なクリンエアー供給装置が使え、外気との遮断性が高くなり、チャンバーの衛生性・安全性が高い充填装置にすることができる。 As described above, this revolving door structure allows a highly airtight chamber to use a small, inexpensive, quiet, easy-to-maintain clean air supply device, and has a high level of shielding from the outside air, making the chamber hygienic and safe.
