Abstract

The invention relates to a method and an apparatus for compacting flowable solids, in particular powders, flours or similar materials, preferably by packing in packagings or sacks. In order to increase the process reliability, there is provision for evacuation of the solid and its sack packaging to take place in a likewise evacuated environment.

Description

本発明は、請求項１の上位概念部に記載した、流動性固形物、特に粉末、穀粉または類似の物質を、好ましくは分包または袋詰めによって密填するための方法に関する。   The present invention relates to a method for compacting flowable solids, in particular powders, flours or similar substances, as described in the superordinate concept of claim 1, preferably by packing or bagging.

本発明はさらに、流動性固形物を密填するための装置に関する。   The invention further relates to an apparatus for compacting flowable solids.

特許文献１に記載された、ばら物を重量計測供給するための方法の場合には、排出装置が完全に空にされる。この場合、ばら物の量が測定され、後流として考慮される。そのために、排出装置は供給プロセスの間少なくとも一度空運転され、空の排出装置の質量と充填された排出装置の質量が測られ、その差が考慮すべき後流を形成する。   In the case of the method described in Patent Document 1 for weighing and supplying loose materials, the discharge device is completely emptied. In this case, the amount of loose material is measured and considered as wake. For this purpose, the discharge device is idled at least once during the feeding process, the mass of the empty discharge device and the mass of the filled discharge device are measured, and the difference forms the wake to be taken into account.

このような排出装置のための二軸排出スクリューが知られている（特許文献２）。このスクリューのねじ山は互いにかみ合っている。案内作用を低下させないようにするために、排出スクリュー内には負圧が発生している。   A biaxial discharge screw for such a discharge device is known (Patent Document 2). The screw threads are engaged with each other. In order not to lower the guiding action, a negative pressure is generated in the discharge screw.

ばら物は押し固めまたは圧縮によって、すなわち真空引きせずに脱気可能である。この場合、押し固め要素または圧縮要素を取り外した後で、膨張が起こり得る。   Bulk material can be degassed by compaction or compression, ie without evacuation. In this case, expansion can occur after removal of the compaction element or compression element.

特許文献３に記載された、流動性ばら物用の密填方法の場合、密填室にばら物が充填され、続いて密填室が縮小させられる。続いて、密填室が気密に閉鎖され、そして負圧を発生するために再び拡大される。その後で、密填されたばら物が排出口から流出する。   In the case of the close-packing method for flowable bulk material described in Patent Document 3, the bulk material is filled into the tight-fill chamber, and then the tight-fill chamber is reduced. Subsequently, the containment chamber is hermetically closed and expanded again to generate a negative pressure. Thereafter, the closely packed bulk material flows out from the outlet.

特許文献４には、スロートまたは弁を備えた、例えば吸湿製品のための大型容器を、製品充填および真空引きするための方法が開示されている。この場合、容器は真空引きされた室内で製品を充填される。不活性ガスの追加によって真空を適合させることができる。   Patent Document 4 discloses a method for filling and evacuating a large container for a hygroscopic product, for example, equipped with a throat or a valve. In this case, the container is filled with the product in a vacuumed chamber. The vacuum can be adapted by adding an inert gas.

本発明の根底をなす課題は、密填された固形物の貯蔵および搬送を、省スペース的にかつ安定した状況で可能にする、流動性固形物、特に粉末、穀粉または類似の物質を、好ましくは分包または袋詰めによって密填するための方法を提供することである。その際、コストを低減し、プロセスの信頼性を高めるべきである。   The problem underlying the present invention is that flowable solids, in particular powders, flours or similar substances, which enable the storage and transport of compacted solids in a space-saving and stable situation, preferably Is to provide a method for packing by packing or bagging. In doing so, it should reduce costs and increase process reliability.

その際、密填された固形物の貯蔵期間はきわめて長い期間が可能である。   In this case, the storage period of the solid material can be very long.

この課題は請求項１の特徴によって解決される。ばら物用貯蔵室と袋室が充填の前または充填中に真空引きされるので、袋詰めの際にばら物の流動特性を損なうことなく、確実にかつ高度に密填することができる。袋充填は事実上「通常の状態」のように行われる。   This problem is solved by the features of claim 1. Since the bulk storage chamber and the bag chamber are evacuated before or during filling, the flow characteristics of the bulk can be reliably and highly sealed without sacrificing the flow characteristics of the bulk. The bag filling is practically performed in the “normal state”.

有利な実施形態は従属請求項に開示されている。   Advantageous embodiments are disclosed in the dependent claims.

例えば小麦粉末の密填は、保持期間を引き延ばし（酸素供給しない）、包装された容積の低減をもたらす。さらに、包装容器の積層性と、その取扱またはパレットによる運搬が改善される。さらに、虫の成長またはカビの繁殖と、脂肪の酸化が抑制される。   For example, wheat flour compaction extends the retention period (no oxygen supply) and results in a reduction in the packaged volume. Furthermore, the stackability of the packaging container and its handling or transport by pallet is improved. In addition, insect growth or mold propagation and fat oxidation are inhibited.

本発明はさらに、流動性固形物、特に粉末、穀粉または類似の物質を、好ましくは分包または袋詰めによって密填するための装置に関する。装置は貯蔵室と、この貯蔵室の後に配置された袋室を有し、この貯蔵室と袋室の両方が真空引き可能である。   The invention further relates to a device for compacting flowable solids, in particular powders, flours or similar substances, preferably by packing or bagging. The apparatus has a storage chamber and a bag chamber located after the storage chamber, and both the storage chamber and the bag chamber can be evacuated.

真空の形成はできるだけ短時間で行うべきであり、場合によって予め真空引きして行うべきである。   The formation of the vacuum should be performed in as short a time as possible, and in some cases it should be performed in advance by evacuation.

さらに、ホース状袋の充填を行うことができる。この場合、袋用接続短管の代わりに、袋形成装置が使用され、製品が予め秤量される。   Furthermore, the hose-like bag can be filled. In this case, a bag forming device is used instead of the connecting short tube for bags, and the product is weighed in advance.

ホース状袋のような袋のための本発明に係る装置は、回転式ステーションのような単一ステーションに統合可能である。回転式ステーションではさらに、真空引きを段階的にまたは予め行うときわめて有利である。脱気の代わりに、先行するステーションの負圧を利用することができる。   The device according to the invention for bags such as hose-like bags can be integrated into a single station such as a rotary station. Furthermore, it is very advantageous for the rotary station to perform the evacuation stepwise or in advance. Instead of degassing, the negative pressure of the preceding station can be used.

次に、図に基づいて本発明の実施形態を詳しく説明する。   Next, embodiments of the present invention will be described in detail with reference to the drawings.

密填装置の原理図である。It is a principle figure of a compaction apparatus.

装置は穀粉等のための貯蔵室１と、その下に設けられた袋室２を有する。この両室１、２の間には、遮断機構としてのスライダ５と、袋室内に突出する接続短管６が配置されている。両室は真空接続部４を備えている。貯蔵室１はさらに、蓋３によって密閉可能な充填口を備えている。   The apparatus has a storage chamber 1 for flour and the like, and a bag chamber 2 provided therebelow. Between the two chambers 1 and 2, a slider 5 as a blocking mechanism and a connecting short pipe 6 projecting into the bag chamber are arranged. Both chambers are provided with a vacuum connection 4. The storage chamber 1 further includes a filling port that can be sealed by the lid 3.

接続短管６（袋用接続短管）には、充填すべき袋（図示せず）が通常の方法で懸吊される。   A bag (not shown) to be filled is suspended from the connecting short pipe 6 (the connecting short pipe for bags) by a usual method.

負圧の作用によって両室が互いに保持されるので、基本的には固定要素は不要である。しかし、安全のためにこのような固定要素を配置してもよい。   Since the two chambers are held together by the action of the negative pressure, basically no fixing element is required. However, such a fixing element may be arranged for safety.

さらに、袋を所定の形にする図示していない要素を、袋室２内に設けることができる。   Furthermore, an element (not shown) for making the bag into a predetermined shape can be provided in the bag chamber 2.

袋に穀粉を詰めるために貯蔵室に穀粉を充填し、袋室２内または接続短管６に袋を準備した後で、蓋３とスライダ５を閉じた状態で、両室１、２は充分な負圧が達成されるまで真空接続部４を経て均一に真空引きされる。続いて、接続短管６のクランプが閉じられ（袋が懸吊され）、所望な袋充填が達成されるまでスライダが開放される。続いて、スライダが閉鎖され、袋が気密に閉じられる。それに続いて、両室１、２が通気されて標準圧力となり、接続短管のクランプが弛められ、図示していない開口を通って袋室２から袋が押し出される。   To fill the bag with flour, the storage chamber is filled with flour, and after the bag is prepared in the bag chamber 2 or the connecting short tube 6, both chambers 1 and 2 are sufficient with the lid 3 and the slider 5 closed. A uniform vacuum is drawn through the vacuum connection 4 until a negative pressure is achieved. Subsequently, the clamp on the connecting short tube 6 is closed (the bag is suspended) and the slider is opened until the desired bag filling is achieved. Subsequently, the slider is closed and the bag is closed airtight. Subsequently, both chambers 1 and 2 are vented to a standard pressure, the connection short tube clamp is loosened, and the bag is pushed out of the bag chamber 2 through an opening (not shown).

接続短管６は袋閉鎖装置を備えていてもよい。貯蔵室１の手前に計量供給装置が接続配置されている。   The connecting short tube 6 may be provided with a bag closing device. A metering device is connected in front of the storage chamber 1.

スライダ５の密閉時に、貯蔵室１が複数の袋に充填するための製品を収容してもよい。それによって、袋詰めコストおよび脱気コストが低減される。そのために、貯蔵室１は計量供給装置を備えている。   When the slider 5 is sealed, the storage chamber 1 may contain a product for filling a plurality of bags. Thereby, bagging costs and degassing costs are reduced. For this purpose, the storage chamber 1 is equipped with a metering device.
