Description
本発明は、少なくとも1つの上部ヘッド部分と少なくとも1つの下部ヘッド部分とを有する多重噴射ヘッドを備えた少なくとも1つの押し出し機を使用するようにした押し出し方法に関するものである。 The present invention relates to an extrusion method that uses at least one extruder with a multiple jet head having at least one upper head portion and at least one lower head portion.
本発明は、さらに、少なくとも1つの上部ヘッド部分と少なくとも1つの下部ヘッド部分とを有する多重噴射ヘッドを備えた少なくとも1つの押し出し機を使用するようにした押し出し装置に関する。 The invention further relates to an extrusion apparatus adapted to use at least one extruder comprising a multiple jet head having at least one upper head portion and at least one lower head portion.
本発明は、タイヤ用走行面ストライプを押し出し成形する技術分野に関わる。 The present invention relates to the technical field of extruding tire running surface stripes.
従来慣用の対応するエラストマーストライプの製造では、押し出し機を使用して、必要なゴム混合物が製造される。押し出し機は、ヘッド下部部分とヘッド上部部分とを有する押し出しヘッドに接続されている。 In the production of the corresponding conventional elastomeric stripes, the necessary rubber mixture is produced using an extruder. The extruder is connected to an extrusion head having a head lower portion and a head upper portion.
特に品質的に高価値で高価なタイヤの分野では、トレッドによってはわずかなロットサイズしか生産されない。ロットサイズは特に使用する材料混合物に関して異なっている。生産交替の場合には、押し出し機と押し出しヘッドとの双方を空走行させてクリーニングしなければならない。特に押し出し機の空走行とクリーニングとは時間の浪費である。クリーニング時間を含めた、ゴム混合物を交換するために必要な典型的な時間は、最近では10分ないし15分の範囲にある。 Especially in the field of high-quality and expensive tires, only a small lot size is produced depending on the tread. The lot size is particularly different for the material mixture used. In the case of production shift, it is necessary to clean both the extruder and the extrusion head while running idle. In particular, idle running and cleaning of the extruder is a waste of time. The typical time required to change the rubber mixture, including cleaning time, is currently in the range of 10 to 15 minutes.
今日では、タイヤの生産者は、生産が多面的になるにしたがって種々の挑戦を強いられる。以前、消費者が1つのタイヤサイズで3つのタイヤタイプを選択できたとすれば、今日では10個のタイヤタイプに対し選択権がある。今日ではUHPタイヤばかりでなく、ウルトラウルトラハイパフォーマンスも話題になっている。 Today, tire producers are faced with various challenges as production becomes multifaceted. Previously, if a consumer was able to select three tire types for one tire size, there is now a choice for 10 tire types. Today, not only UHP tires, but also ultra ultra high performance has become a hot topic.
その結果、生産のロットサイズが低下する。部分的には40個のタイヤを生産すればよく、これは押し出し成形において100mの生産に対応している。1つの押し出しラインには2つの製法しかないが、部分的には3つの製法もある。装置の純生産量は、理論的に使用できる時間の60%まで低下する。 As a result, the production lot size decreases. In part, 40 tires may be produced, which corresponds to 100 m production in extrusion. There are only two manufacturing methods per extrusion line, but in part there are also three manufacturing methods. The net production of the device is reduced to 60% of the theoretically usable time.
それ故、タイヤ生産者は、装置の活用度をかなり改善するという目的をもって、押し出し成形でのより多くの融通性を期待している。射出通路のクリーニングという手動による非生産的な作業工程はダイレクトな生産工程から削除すべきであり、生産中に並行的に実施すべきである。 Therefore, tire producers expect more flexibility in extrusion with the goal of significantly improving equipment utilization. The manual non-productive work process of cleaning the injection passage should be eliminated from the direct production process and should be performed in parallel during production.
1つの観点は、CAPコンポーネントの混合物交換の際の交換時間を減少させることであり、その際ベースとウィングの構成要素とは交換しない。 One aspect is to reduce the exchange time when changing the mixture of CAP components, without replacing the base and wing components.
本発明の課題は、押し出し成形の際の融通性が向上するように、冒頭で述べた種類の方法を改善することである。 The object of the present invention is to improve a method of the kind mentioned at the outset in order to improve the flexibility during extrusion.
本発明の他の課題は、押し出し成形の際の融通性が向上するように、冒頭で述べた種類の装置を改善することである。 Another object of the present invention is to improve an apparatus of the kind mentioned at the outset in order to improve the flexibility during extrusion.
上記課題は、方法に関しては、上部ヘッド部分を交換可能に配置することによって解決される。 The above problems are solved with respect to the method by arranging the upper head part interchangeably.
また上記課題は、装置に関しては、上部ヘッド部分が交換可能に配置されていることによって解決される。 Moreover, the said subject is solved by the upper head part being arrange | positioned so that replacement | exchange is possible regarding an apparatus.
上部ヘッド半部分はスタンバイ状態でクリーニングすることができ、続いてその都度必要なゴム混合物を前もって充填できる。生産交替の際には、それまで生産中であった上部ヘッド半部分をロック解除して側方へ変位させる。これによって、準備されていた第2の上部ヘッド半部分を作業位置へもたらし、ロックする。したがって噴射ヘッドは生産準備状態にある。 The upper head half can be cleaned in the standby state and subsequently filled with the required rubber mixture each time. When changing production, the upper head half that was being produced is unlocked and displaced sideways. This brings the prepared second upper head half to the working position and locks it. Therefore, the ejection head is ready for production.
次に、本発明を図面を用いて説明する。
本発明の1実施形態によれば、キャップエクストルーダを備えた2つの上部ヘッド半部分は横方向に走行可能である。エクストルーダを備えた上部ヘッド半部分は交換される(軸線方向に走行可能)。生産の間、1つのエクストルーダは空走行され、上部ヘッド半部分はクリーニングされる。 According to one embodiment of the present invention, the two upper head halves with cap extruders can run in the lateral direction. The upper head half with the extruder is replaced (can run in the axial direction). During production, one extruder is run idle and the upper head half is cleaned.
ヘッド体は、水平方向において上部ヘッド半部分と下部ヘッド半部分とに分割される。上部ヘッド半部分と下部ヘッド半部分とは、垂直に配置した閉鎖シリンダを用いて互いにロックされる。下部半部分は基台上に固定され、上部半部分は側方へ変位可能であり、第2の上部半部分と交換することができる。 The head body is divided into an upper head half and a lower head half in the horizontal direction. The upper head half and the lower head half are locked together using a vertically arranged closure cylinder. The lower half is fixed on the base and the upper half is laterally displaceable and can be exchanged for a second upper half.
下部ヘッド半部分は、トリプレックスの場合、折り畳み可能な下部分および折り畳み可能な中間部分と結合され、固有のロックシステムを用いてゴム出口に対し固定されている。 The lower head half, in the case of a triplex, is combined with a foldable lower part and a foldable intermediate part and is secured to the rubber outlet using a unique locking system.
上部ヘッド半部分はそれぞれ折り畳み可能な上部部分と結合されている。このケースでも、これらの部分は固有のロックシステムを用いてゴム出口に対し固定される。 Each upper head half is coupled to a foldable upper portion. Again, these parts are secured to the rubber outlet using a unique locking system.
各上部ヘッド半部分はエクストルーダと結合されている。これらのユニットは支持台上に変位可能に取り付けられている。 Each upper head half is connected to an extruder. These units are movably mounted on a support base.
前記ユニットは図1および図2に図示されている。 The unit is illustrated in FIGS.
本発明の他の実施形態によれば、交換可能な中間部分はスタンバイ状態でクリーニングされる。生産を転換する場合、それまで生産中であった中間部分のロックを解除して、側方へ回動させる。外側へ回動可能な両中間部分は一緒に垂直方向に走行させる。クリーニングされた第2の中間部分は射出ヘッド内へ回動させる。次に、上部部分により射出ヘッドとのインターロッキングを行う。このとき射出ヘッドは生産準備状態にある。 According to another embodiment of the invention, the replaceable intermediate part is cleaned in a standby state. When changing production, the middle part that was being produced is unlocked and turned sideways. Both intermediate parts that can be pivoted outwardly travel together in the vertical direction. The cleaned second intermediate portion is rotated into the injection head. Next, the upper part is interlocked with the injection head. At this time, the injection head is ready for production.
本発明の他の実施形態によれば、装置は、上側の2つの中間部分と、下側の2つのキャップエクストルーダとから成る。 According to another embodiment of the invention, the device consists of two upper middle parts and two lower cap extruders.
中間部分は、側部の昇降・回動装置と、エクストルーダの空走行、生産中の中間部分のクリーニングによって交換する。その際に以下のステップを実施する。
−カセット回動装置を(コールバッハクワドKorbach Quadのような)DSへ
−中間部分交換装置をOSへ
−外側へ回動可能な2つの中間部分を一緒に垂直方向へ走行可能(たとえば液圧で)
−ストロークの上部/下部位置はそれぞれ525mm
−それぞれの終端位置で1つの中間部分をヘッド内へ回動させる
−上部部分によるヘッドとのインターロック
The intermediate part is replaced by a lifting / rotating device on the side part, an extruder running idle, and a cleaning of the intermediate part being produced. At that time, the following steps are performed.
-Cassette rotating device to DS (such as Korbach Quad)-Intermediate part changer to OS-Two intermediate parts that can be rotated outwards can travel together vertically (eg hydraulically) )
-The upper / lower position of the stroke is 525mm each
-Turn one intermediate part into the head at each end position-Interlock with the head by the upper part
他の実施形態は、上部に2つの中間部分と、上部に2つのキャップエクストルーダとを重設して含んでいる。1つのエクストルーダはヘッドと固定されている(中間部分による空走行)。 Other embodiments include two intermediate portions on top and two cap extruders on top. One extruder is fixed to the head (running in the middle).
押し出し機はねじで固定されている。空走行は中間部分によって側方へ行われる。クリーニングは、中間部分内の適当な中空室によって行われる。クリーニングに対しては好適なアクセス性がある。 The extruder is fixed with screws. The idling is done laterally by the middle part. Cleaning is performed by a suitable hollow chamber in the intermediate part. There is suitable accessibility for cleaning.
詳細は図4および図5に図示されている。 Details are illustrated in FIGS.
次の実施形態は、上部の2つの中間部分と、上部の2つのキャップエクストルーダとを重設して含んでいる。押し出し機は軸線方向に走行可能である。 The next embodiment includes two upper middle portions and two upper cap extruders. The extruder can run in the axial direction.
中間部分はクリーリング用の中空室を有していない。押し出し機は液圧クランプを用いてヘッドに固定されている。スタンバイ状態の押し出し機は、中央部分の空走行とクリーニングとのために戻る。途中に閉鎖シリンダがあるので、クリーニングに対するアクセス性は悪い。 The middle part does not have a hollow chamber for cleaning. The extruder is fixed to the head using a hydraulic clamp. The extruder in the standby state returns for idle running and cleaning of the central part. Since there is a closed cylinder in the middle, the accessibility to cleaning is poor.
詳細は図6および図7に図示されている。 Details are illustrated in FIGS.
他の実施形態は、上部の2つの中間部分と、2つのキャップエクストルーダとを互いに横に並べてV字配置で含んでいる。押し出し機はヘッドと固定して取り付けられている。中間部分による空走行が生じる。 Other embodiments include two upper middle portions and two cap extruders arranged side by side in a V-shaped arrangement. The extruder is fixedly attached to the head. Idle running occurs in the middle part.
押し出し機はねじで固定されている。空走行は中間部分によって側方に生じる。クリーニングは、中間部分内の適当な中空室によって行われる。クリーニングに対しては好適である。欠点は、通路が非対称であることと、バランスをとるのが困難なことである。 The extruder is fixed with screws. The idling occurs laterally by the middle part. Cleaning is performed by a suitable hollow chamber in the intermediate part. Suitable for cleaning. The disadvantage is that the passage is asymmetric and difficult to balance.
個々の構成は図8および図9に図示されている。詳細は図10と図11とから見て取れる。 Individual configurations are illustrated in FIGS. Details can be seen from FIGS.
次の実施形態は、上部の2つの中間部分と、2つのキャップエクストルーダとを互いに横に並べてV字配置で有し、液圧クランプを用いてヘッドに固定されている。押し出し機は軸線方向に走行可能である。 In the next embodiment, the upper two middle parts and the two cap extruders are arranged side by side in a V-shaped arrangement and fixed to the head using a hydraulic clamp. The extruder can run in the axial direction.
スタンバイ押し出し機は空走行のために戻り、中央部分をクリーニングする。クリーニングに対しては好適なアクセス性がある。欠点は非対称な通路とバランスの困難性である。 The standby extruder returns to run idle and cleans the central part. There is suitable accessibility for cleaning. Disadvantages are asymmetric passages and difficulty in balancing.
本発明の両実施形態によれば、対応する交換時間が著し減少する。 According to both embodiments of the present invention, the corresponding exchange time is significantly reduced.
本発明の第1実施形態によれば、エクストルーダヘッドの領域に2つの中間部分が使用される。1つの中間部分をエクストルーダヘッドの領域で使用することはすでに公知である。 According to the first embodiment of the invention, two intermediate parts are used in the region of the extruder head. The use of one intermediate part in the area of the extruder head is already known.
付加的な中間部分は押し出しヘッドから位置決め可能である。押し出しヘッド内にまだ残っている中間部分により生産を続行する。押し出しヘッドから走行し、またはそこから回動した中間部分は、清掃することができる。クリーニングした中間部分が押し出しヘッド内へ新たに走入した後、生産を続行している間にすでに次の必要な材料混合物が供給された第2の押し出し機の接続を行う。第2の中間部分が走入した直後、第2の押し出し機から供給される新たな材料混合物を用いて生産を続行することができる。最後に、もはや作動していない押し出し機を空走行させてクリーニングする。 The additional intermediate part can be positioned from the extrusion head. Production continues with the intermediate part still remaining in the extrusion head. The intermediate part that travels from or is pivoted from the extrusion head can be cleaned. After the cleaned intermediate part has newly entered the extrusion head, the second extruder, which has already been supplied with the next required material mixture, is connected while production continues. Immediately after the second intermediate part enters, production can be continued with a new material mixture fed from the second extruder. Finally, the extruder that is no longer operating is run idle and cleaned.
本発明のこの第1実施形態によれば、生産を交替させるために必要な時間はほぼ6分にすぎない。したがって交替時間をほぼ半分にすることができる。 According to this first embodiment of the invention, the time required to alternate production is only about 6 minutes. Therefore, the replacement time can be almost halved.
本発明の第2実施形態によれば、半分の2つの上部押し出しヘッドが使用される。これら半分のヘッドのそれぞれは1つの押し出し機に付設され、この押し出し機とともに走行可能である。生産交替の場合、新たな押し出し機に所望の材料を供給し、生産交替のために、当該押し出し機を付設の半分の押し出しヘッドとともに生産位置へ走行させる。続いて、このとき作動していない押し出し機と付設の半分のヘッドとを空走行させてクリーニングする。 According to a second embodiment of the invention, two upper half extrusion heads are used. Each of these half heads is attached to one extruder and can run with this extruder. In the case of a production shift, a desired material is supplied to a new extruder, and the extruder is moved to a production position together with an additional half of the extrusion head for a production shift. Subsequently, the extruder which is not operating at this time and the attached half head are run idle for cleaning.
本発明のこの第2実施形態での時間節減は、技術水準による交替時間及びクリーニング時間に比べてほぼ3分である。 The time saving in this second embodiment of the invention is approximately 3 minutes compared to the replacement time and cleaning time according to the state of the art.
